Di--chloro-bis[(2,2':6,2''-terpyridine-³N)copper(II)] diperchlorate: the triclinic polymorph

G. Gasser, G. Labat and H. Stoeckli-Evans

Abstract: The title compound, [Cu₂Cl₂(C₁₅H₁₁N₃)₂](ClO₄)₂, crystallized from water as the triclinic polymorph. There are two independent centrosymmetric binuclear dications, [Cu₂(terpyridine)₂Cl₂]²⁺, and four perchlorate anions per unit cell. Each Cu atom has a distorted square-pyramidal geometry. In the crystal structure, the cations are bridged by the perchlorate anions via C-HO hydrogen bonds, thereby forming a three-dimensional network.
