title: (2,2'-Bipyridine-κN,N')chlorido(2-hy-droxy-2,2-diphenyl-acetato-κO,O)copper(II).
abstract: The Cu(II) atom in the title complex, [Cu(C(14)H(11)O(3))Cl(C(10)H(8)N(2))], exists within a ClN(2)O(2) donor set defined by a chloride ion, an asymmetrically chelating carboxyl-ate ligand, and a symmetrically chelating 2,2'-bipyridine mol-ecule. The coordination geometry is square pyramidal with the axial site occupied by the O atom forming the weaker Cu-O inter-action. The hy-droxy group forms an intra-molecular hydrogen bond with the axial O atom, as well as an inter-molecular O-H⋯Cl hydrogen bond. The latter leads to the formation of [100] supra-molecular chains in the crystal, with the Cu(II) atoms lying in a line.
