摘要

In the title coordination polymer, {[CdBr2(C5H9NO2)]·H2O}n, the CdII ion is coordinated by four bromido ligands and two carboxylate oxygen atoms of two symmetry-related proline ligands, which exist in a zwitterionic form, in a distorted octahedral geometry. There is an intramolecular N—H⋯O hydrogen bond between the amino group and the carboxylate fragment. Each coordinating ligand bridges two CdII atoms, thus forming polymeric chains running along the c-axis direction. The water molecules of crystallization serve as donors for the weak intermolecular O—H⋯O and O—H⋯Br hydrogen bonds that link adjacent polymeric chains, thus forming a three-dimensional structure. N—H⋯O and N—H⋯Br hydrogen bonds also occur.
