Crystal and molecular structure of di-µ-hydroxo-bis[bipyridylcopper(II)] diperchlorate

Abstract

The crystal structure of the title compound has been determined from three-dimensional X-ray diffractometer data. Crystals are monoclinic with unit-cell dimensions, a= 13.614(3), b= 15.244(3), c= 6.279(1)Å, β= 113.64(2)°, space group C2/m,Z= 2. The structure was solved by the heavy-atom techniques, and refined by block-diagonal least-squares methods to R 0.054 for 1 916 independent reflections. The compound is binuclear. The geometry of the copper atom is square planar with two more distant Cu ⋯ O (perchlorate) contacts at 2.797 Å completing on octahedron. Cu ⋯ Cu is 2.871, Cu–O 1.918, and Cu–N 1.990 Å.
