Abstract Acetylacetone reacts with 3-aminopropyl[tris(trimethylsilyloxy)]silane to give a mixture of the isomers 4-[3′-tris(trimethylsilyloxy)silylpropyl]iminopent-2-en-2-ol
(90%) and 4-[3′-tris(trimethylsilyloxy)silylpropyl]aminopent-3-en-2-one (10%). According to 1H and 13C NMR data, both isomers exist in the cis-and trans-forms. Anhydrous europium(III) and erbium(III) tris{4-[3′-tris(trimethylsilyloxy)silylpropyl]iminopent-2-en-2-olates} were
obtained from the mixture of the isomers and the corresponding propan-2-olates Eu(OPri)3 and Er(OPri)3. The resulting complexes are transparent air-stable liquids that are distillable in vacuo and well soluble in photopolymerizable
polyorganosiloxane caoutchoucs and urethane acrylate oligomers. The volatility parameters of the europium(III) complex were
studied.

Abstract The process of Gd3+ complexation with 4-dihydroxyborophenylalanine (DHBPA) in aqueous solutions was studied by the contact conductometry, IR,
and X-ray photoelectronic spectroscopy methods. The complex formation reactions of Gd3+ with DHBPA were found to occur in steps, depending on the metal: ligand ratio. In the final reaction product, i.e., the chelate
complex [Gd(DHBPA)3], each molecule of a ligand occupies two coordination sites.

Abstract The reactions of Mn(II), Fe(II), Co(II), Ni(II), Cu(II), and Cd with 2,3-dihydroxyquinoline (H2L) were used to synthesize and identify the complexes M(HL)2 · 2H2O (M = Mn, Ni, Cu), Fe(HL)OH · 2H2O, Co(HL)OH · H2O, Cd(H2L)Cl2, where H2L participates in the coordination in the monoanionic or neutral forms with the formation of the chelate cycles. Single crystal
was isolated and the crystal structure of H2L was determined. The spectral characteristics of a neutral and anionic form of the ligand were measured, and its complexation
with MCl2 was studied in the ethanol solutions. The acidity constant of H2L and the formation constants of the complexes in solutions were calculated.

Abstract A new Schiff base ligand as salt (KL) was synthesized using potassium salt of DL-β-phenylalanine and 2-hydroxy-1-naphthaldehyde.
Two binuclear complexes of this ligand, [M2L2(CH3COO)2] (M = Cu(II), Ni(II)) have been synthesized and characterized by elemental analyses, IR, UV spectra, and molar conductance.
Their prohibitive action on the superoxide anion free radical (O2−·) was estimated by the NBT illumination deoxidizing method (Methionine-lactoflavin illumination method). The results suggested
that the ligand and its complexes had the prohibitive action on O2−·.

Abstract The complexes [CuLCl2] (I), [CoLCl2] (II), and CuLBr2 (III) (where L is the derivative of optically active 5-pyrazolone prepared from the terpene (+)-3-carene) were obtained and characterized.
According to X-ray diffraction data, crystal structures I and II (orthorhombic crystal system) are built from mononuclear acentric molecules. In the resulting complexes, the Cu2+ or Co2+ ion coordinates two N atoms of the chelating bidentate ligand L and two Cl atoms, thus making a distorted tetrahedron. Intermolecular
contacts and the hydrogen bonds Cl(1)…H-O(1) give rise to columns parallel to axis y. For complexes I and III, μeff = 1.83 and 1.81 μB, respectively; these values correspond to the electronic configuration d9. For complex II, μeff = 4.42 μB, which suggests the tetrahedral structure of the coordination entity CoCl2N2. Complexes I and III were studied by EPR spectroscopy.

Abstract In the reaction of Na2Se with [Fe(CO)5] in isopropanol with subsequent acidification with HCl, which is used to synthesize [(μ-H)2Fe3(μ3-Se)(CO)9] (II), the cluster [(μ-H)2Fe5(μ3-Se)2(CO)14] (I) was detected. In assumption that compound I could serve as a suitable synthon for preparing the bulky heterometallic clusters, its reactions with the Rh-containing complexes
were studied. The reaction of I with [Rh(CO)2Cp*] (Cp* is pentamethylcyclopentadienyl) was found to give a mixture of the products. The main reaction products were isolated
and their structures were determined: [Fe2Rh(μ3-Se)2(CO)6Cp*], [Fe2Rh(μ3-Se)(μ3-CO)(CO)6Cp*], [FeRh2(μ3-Se)(μ-CO)(CO)3Cp2*], [Fe2Rh2(μ4-Se)(μ-CO)4(CO)2Cp2*]. Potassium hydride treatment of II with subsequent addition of [Cp*Rh(CH3CN)3](CF3SO3)2 leads to the well-known cluster complex [Fe3Rh(μ4-Se)(CO)9Cp*]. A set of the reaction products indicates that the {Fe5Se2} core cannot be used as one-piece “building block” in the synthesis of heterometallic clusters.

were determined. The sublattices contain chemically identical A atoms in the crystal structures of 232006 inorganic, coordination,
and organoelement compounds. The VDP of A atoms have most often 14 faces, the Fedorov cuboctahedron being the most abundant
VDP type. The effect of the nature of the A atoms on the characteristic A-A interatomic distances in the homoatomic sublattices
of the crystal structures was considered.

Abstract A novel chiral 2-D layer coordination polymer [Co(Pydc)(H2O)2] · H2O (Pydc = Pyridine-2,5-dicarboxylate) was hydrothermally synthesized and characterized by elemental analysis, IR spectra and
TG analysis. Single-crystal X-ray diffraction shows that Co(1) was connected by the oxygen atom and nitrogen atom of different
carboxyls and form a helical-shaped {O(3)-Co-N}n chain along 21 helical axes. The adjacent 1-D {O(3)-Co-N}n helical-shaped chains are developing along 21 helical axes with the same direction and are connected by O(4) to form an ordered 2-D layer. All the molecules exist in the
same optical activity that imparts the chiral nature to the whole compound.

Abstract A novel compound containing tetraphenylphosphonium and nickel dicarbollyl, [[P(C6H5)4][Ni(B9C2H11)2] · CCl4 (I) was synthesized and studied by X-ray diffraction and EPR methods. The crystals are monoclinic: C29H42B18PCl4Ni (M = 816.69), space group P2/c, the unit cell parameters a = 13.3964(5), b = 7.0556(2), c = 20.6610(8) Å, β = 94.9070(13)°, V = 1945.7(2) Å3, Z = 2, ρ(calcd.) = 1.394 g/cm3, T = 100 K, F(000) = 834, μ = 0.081 mm−1. The structure was solved by the direct and Fourier methods and refined by the full-matrix least-squares method in the anisotropic
(isotropic for the hydrogen atoms) approximation (R1 = 0.032 for 4027 Ihkl ≥ 2σ(I), 19886 measured and 5379 independent Ihkl; X8 APEX Bruker difractometer, λMoKα, graphite monochromator, ϕ/ω scan mode). At 100 K, the crystal contains the intermolecular hydrogen bonds B–H…Cl that favor
the formation of infinite chains of the alternating anions and solvate molecules along the z axis of the unit cell. The single-crystal EPR study of complex I showed that the temperature changes of the cell parameters
induce changes in the parameter of the g-factor g1 directed along Cb-Ni-Cb. The cell parameters are increased and the g1 value is gradually decreased with the increasing temperature. The temperature study of the EPR spectra of the powdered compound
I revealed also jumpwise changes in g2 and g3 with hysteresis at 183–203 K depending on the direction of the temperature changes. The differences observed in the EPR spectra
of the powders and single crystal of compound I in both the g-factor and the temperature dependence of its components are supposed to be caused by the CCl4 vacancies formed in the crystal structure of a complex as a result of the partial removal of the solvate CCl4 molecules when grinding the sample and by the change in the lability of the solvate molecules of a solvent with temperature.
