μ-Succinato-bis[aqua(2,2′:6′,2′′-terpyridine)copper(II)] dinitrate dihydrate

Abstract

The title compound, [Cu2(C4H4O4)(C15H11N3)2(H2O)2](NO3)2·2H2O, was synthesized under hydro­thermal conditions. The dinuclear copper complex is located on a crystallographic inversion centre. The CuII ion is penta­coordinated in a tetra­gonal–pyramidal geometry, with one O atom of a succinate dianion and three N atoms of a 2,2′:6′,2′′-terpyridine ligand occupying the basal plane, and a water O atom located at the apical site. In the crystal structure, O—H⋯O hydrogen bonding links the mol­ecules into a chain parallel to the a axis.
