catena-Poly[[[(acetato-κ2O,O′)aqua-cadmium(II)]-μ-l-threoninato-κ3N,O:O′] monohydrate]

摘要

The title compound, {[Cd(C 2 H 3 O 2 )(C 4 H 8 NO 3 )(H 2 O)]·H 2 O} n , was synthesized from the reaction between L -threonine and cadmium acetate dihydrate. The complex consists of the Cd II metal ion bonded to bidentate threonine and acetate anions, and one water mol-ecule. The carboxyl-ate group of L -threonine bridges two metal cations related by the crystallographic screw axis parallel to [010], to form a one-dimensional polymeric structure in the crystal. The asymmetric unit is completed by one lattice water mol-ecule, which is involved in hydrogen bonds.
