Abstract
The crystal and molecular structure of dichlorobis(pyridine-1-oxide) copper(II), C10H10N2O2Cl2Cu, has been determined from 3931 reflections measured on a Picker four-circle diffractometer, using the θ/2θ scan technique and MoKα radiation. The crystals are monoclinic, space groupP21/c,a = 6.900(4),b = 15.065(7),c = 12.065(5) Å, β = 97.00(4) ° andZ = 4. The structure was solved by Fourier methods and refined by full-matrix least-squares. The final conventionalR-factor was 0.033. The compound is dimeric, and the units of the dimer are held together by oxygen bridges. The coordination polyhedron for Cu is a tetragonal pyramid, with two bridging oxygens and two chlorines in the basal plane. The apical position is occupied by oxygen in the non-bridging ligand. The Cu−Cu distance in the dimer is 3.306(1) Å.
