catena-Poly[[copper(I)-μ-2,6-bis-[4-(pyridin-2-yl)thia-zol-2-yl]pyridine] hexa-fluoridophosphate acetonitrile monosolvate] from single-crystal synchrotron data.

The title complex, {[Cu(C21H13N5S2)]PF6·CH3CN} n , was formed immediately on adding together a methanol solution containing copper(I) ions and a methanol solution of 2,6-bis-[4-(pyridin-2-yl)thia-zol-2-yl]pyridine. Crystallographic studies of the complex reveal a coordination polymer with the ligand acting as a bis-(bidentate) ligand with the pyridine N atom not coordinating a metal centre. The Cu(I) atom is four-coordinate with approximately tetra-hedral stereochemistry: the N4 donor set is provided by bipyridine-like moieties of the two heterocyclic ligands. Parallel chains of the coordination polymer run along the b-axis direction with the disordered (0.50:0.50 occupancy ratio) PF6 (-) anions and acetonitrile solvent mol-ecules located between the chains.
