Crystal structure of copper(II) chelate with para-(tert-butyl)benzoic acid N′,N′-dimethylhydrazide

Abstract

X-Ray diffraction analysis was performed for the copper(II) chelate with para-(tert-butyl)benzoic acid N′,N′-dimethylhydrazide, Cu(p-(tert-Bu)C6H4CONHNMe2)2 (I). The reagent functions as a bidentate (O,N(2)) ligand giving a five-membered copper-containing ring. The molecule is centrosymmetric. The Cu atom and the metal rings lie in the same plane. The coordination polyhedron of copper is a slightly distorted square. The crystals are monoclinic: a = 16.2634(14) A, b = 9.0415(8) A, c = 9.6415(9) A, α = 90°, β = 100.052(7)°, Z = 2, space group P21/c.
