Abstract
The title compound, {[Cd(C2H3O2)(C4H8NO3)(H2O)]·H2O} n , was synthesized from the reaction between L-threonine and cadmium acetate dihydrate. The complex consists of the CdII metal ion bonded to bidentate threonine and acetate anions, and one water molecule. The carboxylate 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 molecule, which is involved in hydrogen bonds.

The O—Cd—O bond angles range from 53.95 (14) to 162.36 (14). Hydrogen bonds are formed, with all N—H and O—H groups from the l-threonine and water molecules serving as donor groups (Table 1), affording a
