A new sodium coordination polymer with benzene-1,2,4-tricarboxylic acid, [Na-3(btc)(H2O)(2)] center dot 2H(2)O was prepared by crystallization from DMF solution and characterized by IR, single-crystal X-ray and thermal analyses. The non-centrosymmetric structure contains four crystallographically independent metal centers with six-coordination configuration. Carboxylate oxygen atoms and water molecules bridge the adjacent Na atoms to form a polymeric network. The three-dimensional network contains of almost ellipsoidal channels occupied by the uncoordinated water molecules. On heating, the complex loses water molecules, immediately forming a stable anhydrous compound. The features of IR spectrum are clearly compatible with the structural characteristics of the complex under study.
