Abstract: In the title compound, [Cu(NCS)₂(C₁₀H₈N₂)]_n, the Cu^II ion (site symmetry 2) has an elongated octahedral coordination. Four N atoms of two thiocyanate anions and two 4,4'-bipyridine (4,4'-bipy) ligands are sited at the equatorial positions, while two S atoms of two coordinating thiocyanate anions occupy the axial positions. The complete 4,4'-bipy molecule is generated by the twofold axis and one of its pyridine rings is disordered over two sets of positions. The copper ions are bridged by the 4,4'-bipy ligands, giving rise to a one-dimensional chain. The chains are further linked by the NCS^- anions, through the long axial Cu-S contacts, yielding a two-dimensional network.
