In the mixed-valence Cu^I/Cu^II coordination polymer, [Cu₂Cl₃(C₂₀H₁₄N₄)]_n, the two Cu atoms are bridged to a pair of Cl atoms across a centre of inversion. The monovalent metal atoms is coordinated by a pyridine N atom as well as by three Cl atoms in a tetrahedral CuNCl₃ geometry. The divalent metal atom is N,N',N''-chelated by the heterocycle, and it exists in a square-pyramidal CuN₃Cl₂ geometry; the apical site is occupied by the second bridging Cl atom. The bridging modes of the Cl atoms and the heterocycle give rise to the formation of a layered arrangement parallel to (001).
