Then, their nickel(II) perchlorate complexes were synthesized by the template effect by reaction of 1,4-bis(2-carboxyaldehyde phenoxy)butane, Ni(ClO4)(2) center dot 6H(2)O and various diamines. The metal-to-ligand ratio of Ni-II metal complexes was found to be 1:1. The compounds are coordinated to the central metal as tetradentate O2N2 ligands The Ni-II complexes are proposed to exhibit tetrahedral geometry. Ni-II metal complexes are 1:2 electrolytes as shown by their molar conductivities (Lambda(M)) in DMF (dimethyl formamide) at 10(-3) M. The structure of Ni-II metal complexes is proposed from elemental analysis, f.t.-i.r., u.v.-vis., magnetic susceptibility measurements, molar conductivity measurements and mass spectra.eninfo:eu-repo/semantics/closedAccess[No Keyword]Synthesis and spectral characterization of macrocyclic NiII complexes derived from various diamines, NiII perchlorate and 1,4-bis(2-carboxyaldehydephenoxy)butaneSynthesis and spectral characterization of macrocyclic NiII complexes derived from various diamines, NiII perchlorate and 1,4-bis(2-carboxyaldehydephenoxy)butaneArticle32810121017WOS:0002496661000022-s2.0-3484891543010.1007/s11243-007-0260-0Q2Q3
