Two novel mono- and heptanuclear Ni(II) complexes constructed from new unsymmetric and symmetric Salamo-type bisoximes – Synthetic, structural and spectral studies
heptanuclear Ni(II) complexes, [Ni(HL1)2(EtOH)2]·2EtOH (1) and [Ni7(L2)3(μ3-OMe)2(μ3-OH)6(MeOH)6] (2), have been synthesized by the reaction of Ni(II) acetate with H2L1 and H2L2, respectively. In the Ni(II) complex 1, the ligand H2L1 was partially deprotonated, only NO donor atoms of one salicylidene moiety of the (HL1)− unit coordinate to Ni(II) atom. While all the three H2L2 ligands in the Ni(II) complex
Mono, di and heptanuclear metal(II) complexes based on symmetric and asymmetric tetradentate Salamo-type ligands: Syntheses, structures and spectroscopic properties
heptanuclear metal(II) complexes with chemical formulae [Cu(L1)] (1), [Co2(L2)2]·2CH3CN (2) and [Ni7(L3)3(μ3-OEt)2(μ3-OH)6(EtOH)6] (3) have been synthesized by variational tetradentateSalamo-typeligands based on 3,5-dichlorosalicylaldehyde, and characterized by elemental analyses, FT-IR, UV–Vis spectra and X-ray crystallography. The Cu(II) complex 1 is a mononuclear complex with tetracoordinate Cu(II) atom lies
