Crystal and molecular structure of tris-(2,2′-bipyridyl)copper(II) perchlorate

Abstract

The crystal and molecular structure of the title compounds has been determined from three-dimensional single crystal X-ray diffraction data, collected by counter techniques. Crystals are triclinic, space group P, with Z= 2 in a unit cell of dimensions: a= 12·673(17), b= 18·440(21), c= 7·937(7)Å, α= 90·37(14)°, β= 120·56(13)°, and γ= 98·80(11)°. The structure was refined by full-matrix least-squares methods on alternate sets of atoms to R 0·091 for 3972 observed reflections. The monomeric complex ions exhibit a distorted octahedral configuration, with unequal distortions of the axial Cu–N bonds. Mean distances: Cu–N(eq) is 2·031(6), Cu–N(ax) 2·226(7), and 2·450(7)Å.
