STRUCTURE OF (2,2'-BIPYRIDINE)BIS(DIFLUOROPHOSPHINATO)COPPER(II), (BPY)CU(PF2O2)2

[Cu(C10H8N2)(PF2O2)2], M(r) = 421.7, monoclinic, C2/c, a = 17.706 (4), b = 10.465 (3), c = 7.632 (2) angstrom, beta = 90.99 (2)-degrees, V = 1414 angstrom 3, Z = 4, D(x) = 1.981 g cm-3, lambda-(Mo K-alpha) = 0.71073 angstrom, mu = 18.6 cm-1, F(000) = 836, T = 213 K, R = 0.030 for 858 observed data with I > 3-sigma-(I). Crystals of (bpy)-Cu(PF2O2)2 (bpy = 2,2'-bipyridine) form in the decomposition of [Cu2(bpy)2(phenylacetylene)][PF6]2 in wet 2-butanone-hexane solution. The arrangement of ligands about the Cu atom is that of a tetragonally distorted octahedron. There are two short Cu - O bonds in the plane of the bipyridine ligand and two long bonds to the Cu atom from O atoms in PF2O2- ligands in planar units above and below the plane containing the first Cu atom.
