title: Crystal structure of μ-4-oxidobenzoato-κ2O1:O4-bis-[bis-(1,10-phenanthroline-κ2N,N')copper(II)] bis-(4-hy-droxy-benzoate) 7.5-hydrate.
abstract: The title hydrated complex, [Cu2(C7H4O3)(C12H8N2)4](C7H5O3)2·7.5H2O, is composed of dinuclear CuIIcomplex cations, noncoordinating 4-hy-droxy-benzoate anions and water mol-ecules of crystallization. In the dinuclear complex cation, the CuIIions are bridged by a 4-oxidobenzoate ligand and thus each metal ion is five-coordinated by two chelating 1,10-phenanthroline (phen) mol-ecules and one anionic O atom in a distorted trigonal-bipyramid geometry. In the crystal, aromatic π-π stacking occurs between phen rings of neighbouring dinuclear CuIIcomplex cations, forming two-dimensional supra-molecular systems parallel to (100).
