Crystal structure of copper(II) chelate with para-(tert-butyl)benzoic acid N′,N′-dimethylhydrazide
摘要:
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) , b = 9.0415(8) , c = 9.6415(9) , alpha = 90A degrees, beta = 100.052(7)A degrees, Z = 2, space group P2(1)/c.

The extraction of copper(II) with the para-tert-butylbenzoic acid hydrazide and related N',N'-dimethyl derivative was studied. The composition and structure of the extracted complexes were determined, the mechanism of extraction of copper(II) in different media was suggested, the extraction constant was calculated. The copper(II) complex compounds with these reagents were isolated.
