title: [μ-N,N,N',N'-Tetra-kis(2-pyridyl-meth-yl)butane-1,4-diamine]-bis-[diacetato-cadmium(II)] nona-hydrate.
abstract: The title dinuclear complex, [Cd(2)(CH(3)CO(2))(4)(C(28)H(32)N(6))]·9H(2)O, is located on a crystallographic inversion center. The unique Cd(II) 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 mol-ecules and solvent water mol-ecules are connected into a three-dimensional network via inter-molecular O-H⋯O hydrogen bonds. One of the water mol-ecules lies on a twofold rotation axis.
