Ni(II) complexes with optically active bis(menthane), pinano-para-menthane ethylenediaminodioximes and pinano-para-menthane, bis(pinane) propylenediaminodioximes: Synthesis, structures, and properties

Ni(II) complexes with optically active bis(menthane), pinano-para-menthane... Reactions of Ni(NO3)2 · 6H2O) in EtOH(iso-PrOH) with optically active bis(menthane) ethylene-diaminodioxime (H2L1), pinano-para-menthane ethylenediaminodioxime (H2L2), pinano-para-menthane propylenediaminodioxime (H2L3) and bis(pinane) propylenediaminodioxime (H2L4) were used to synthesize [Ni(H2L1)NO3[NO3 · 2H2O (I), [Ni(HL2)]NO3 (II), [Ni(HL3)]NO3 (III), and [Ni(HL4)]NO3 (IV). X-ray diffraction study of paramagnetic complex I (μeff = 3.04 μB and diamagnetic complexes II and III revealed their ionic structures. A distorted octahedral polyhedron N4O2 in the cation of complex I is formed by the N atoms of tetradentate cycle-forming ligand, i.e., the H2L1 molecule, and the O atoms of the NO 3 − anion acting as a bidentate cyclic ligand. In the cations of complexes II and III, containing a pinane fragment, the coordination core NiN4 has the shape of a distorted square formed on coordination of tetradentate cycle-forming ligands, i.e., anions of the starting dioximes. The structure of diamagnetic complex IV is likely to be similar to the structures of complexes II and III. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Coordination Chemistry Springer Journals
