Bromidotetrakis(2-isopropyl-1H-imidazole-κN³)copper(II) bromide

Abstract

Key indicators: single-crystal X-ray study; T = 120 K; mean (C-C) = 0.005 Å; R factor = 0.033; wR factor = 0.092; data-to-parameter ratio = 17.6.The Cu II atom in the title salt, [CuBr(C 6 H 10 N 2 ) 4 ]Br, is coordinated in a square-pyramidal geometry by four imidazole N atoms and one bromide anion that is located at the apex of the pyramid. The cations and the anions form a twodimensional network parallel to (001) through N-HÁ Á ÁBr hydrogen bonds. Related literature

Copper(II) complexes with substituted imidazole and chlorido ligands: X-ray, UV–Vis, magnetic and EPR studies and chemotherapeutic potential

“…Structural features of copper(II) complexes with imidazole ligands were studied both in the solid state and in solution [14,[30][31][32][33][34][35][36][37][38][39][40][41][42][43][44]. It was found that the central copper(II) ion is usually surrounded by four imidazole ligands and typical coordination number in complexes with imidazole ligand is five or six.…”
