Abstract

The title dinuclear complex, [Cd2(CH3CO 2)4(C28H32N6)] ·9H2O, is located on a crystallographic inversion center. The unique CdII ion displays a 5 + 2 coordination. A distorted square-pyramidal geometry is formed by the dipicolyl-amine unit of the ligand via the N atoms in a meridional fashion and two O atoms of the acetate ligands with short Cd - O distances. The coordination is completed by two loosely bound O atoms of the acetate ligands. The Cd - N distances involving the pyridine N atoms differ slightly from each other and the Cd - N distance involving the tertiary N atom is the longest. In the crystal structure, complex molecules and solvent water molecules are connected into a three-dimensional network via inter-molecular O - H⋯O hydrogen bonds. One of the water molecules lies on a twofold rotation axis.
