Poly[diaqua(μ5-pyridine-3,5-dicarboxylato)strontium]

Abstract

In the structure of the title compound, [Sr(C7H3NO4)(H2O)2] n , the SrII cation is eight-coordinated in form of a distorted dodecahedron by two water O atoms and by five O atoms and one N atom from five pyridine-3,5-dicarboxylate anions. The bridging mode of the anions leads to the formation of a layered network parallel to (100). O—H...O hydrogen bonding between the coordinating water molecules and the carboxylate groups of adjacent layers consolidates the crystal packing. Weak C—H...O interactions are also observed.
