Crystal structure of the CuCl2 complex with two molecules of N',N'-dimethyl-para-tert-butylbenzohydrazide [Cu(p-(t-Bu)C6H4CONHN(Me)2)2]Cl2 ∙ 1.34 Н2О

Resumo

Complex [Cu(HL¹)₂]Cl₂ ⋅ 1.34 Н₂О (HL¹ = p-(t-Bu)C₆H₄CONHN(Me)₂) is studied by X-ray diffraction analysis. The coordination polyhedron of the copper atom is a distorted tetragonal pyramid, whose base is formed by the amine N and O atoms of two ligands HL¹, and one of the chlorine atoms occupies the vertex. The second chlorine atom does not enter into the coordination sphere of copper but is linked through an intramolecular hydrogen bond with the NH group. Reagent HL¹ forms a five-membered metallocycle with the central atom. The metallocycle exists in an envelope conformation with the copper atom in the flap. CIF file CCDC no. 1453151.
