Popis: | The crystal structures of dichlorobis(3,5-diphenylpyrazole-N2)copper(II), [CuCl2(C15H12N2)2], (I), dichlorobis(5-phenylpyrazole-N2)copper(II), [CuCl2(C9H8N2)2], (II), and dichlorobis(1-phenylpyrazole-N2)copper(II), [CuCl2(C9H8N2)2], (III), have been determined from X-ray diffraction data. There are significant differences in the coordination of the Cl− ions to the Cu2+ ion. The coordination of the Cu2+ ion is distorted square pyramidal in compounds (I) and (II), and distorted tetrahedral in (III). All available N—H groups form hydrogen bonds, which are intra- and intermolecular in (I), and intramolecular in (II). An N—H group in (I) forms a bifurcated hydrogen bond. Intermolecular intereactions between neighbouring molecules form dimers and chains in (I) and (II), respectively. |
