Abstract: | In the title neutral coordination polymer, Cd(C6H3ClNO2)2(H2O)2]n, each CdII ion is coordinated by one N and four O atoms from three 2‐chloronicotinate ligands and by two aqua ligands, defining a distorted monocapped octahedral coordination geometry. Adjacent Cd atoms are linked by the pyridyl N atom and the bidentate carboxylate functional group of a 2‐chloronicotinate ligand, forming a one‐dimensional infinite chain along the b axis. The Cd?Cd distance is 8.112 (3) Å. These chains are linked by O—H?O and O—H?N hydrogen bonds into a three‐dimensional network structure. |
