Title

Preparation of the Complexes MᴵᴵL₂·2CH₃OH (M = CO, Ni, Cu, Zn) of the Bidentate Ligand 2-(2′-hydroxy-3′-methylphenyl)-benzimidazole (HL) and the Molecular Structure of CuᴵᴵL₂·2CH₃OH

Abstract

The complexation of the sterically demanding bidentate ligand 2-(2′-hydroxy-3′-methylphenyl)-benzimidazole (HL) with divalent transition metal ions MII (Co, Ni, Cu, Zn), yielded a series of mononuclear complexes of general formula MIIL2·2CH3OH. The crystal structure of the copper(II) complex has been determined and the four coordinate copper(II) centre displays a substantial asymmetric distortion (θ = 39.5°) from a square planar geometry (θ = 0°) towards a tetrahedral geometry (θ = 90°). Crystallographic data: C30H30CuN4O4, Mr = 574.14, triclinic (P1 (No. 2))), a = 11.231 (4), b = 15.399 (5), c = 8.194 (4) A ̊, α = 100.68 (3), β = 103.56 (3), γ = 82.96 (3)°, Z = 2, T = 296 K, Dcalc = 1.413 g cm-3, R(Rw) = 0.044 (0.043). © 1995.
