catena-Poly[[copper(I)-μ-2,6-bis­[4-(pyridin-2-yl)thia­zol-2-yl]pyridine] hexa­fluoridophosphate 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)thia­zol-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 tetra­hedral 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 mol­ecules located between the chains.
