The Polymeric Structure of Aquacadmium Bisnicotinate

The title compound, poly[aquacadmium-bis(μ-nicotinato-κN:κO,κO')], [(Cd(C 6 H 4 NO 2 ) 2 (H 2 O)], consists of a polymeric network in which each nicotinate acts as a bidentate chelating ligand towards one Cd atom through its carboxylate group while simultaneously binding to a second Cd atom through its pyridine N atom. Cd has approximate pentagonal bipyramidal coordination geometry. Water acts as a ligand; it is also involved in hydrogen bonding to nearby carboxylate O atoms, contributing further to the polymeric network interactions
