Poly[[diaquacaesium(I)]bis(μ 3 -3-carboxypyrazine-2-carboxylato)]

Abstract

The asymmetric unit of the title compound, [Cs(C6H3N2O4)(2)(H2O)(2)](n), contains one Cs-I cation on an inversion centre, one 3-carboxypyrazine-2-carboxylate anion and one water molecule. In the crystal structure, each anion is linked to three cations, while each cation is surrounded by six of the anions. In addition, each cation is coordinated by two water O atoms, raising the coordination number to ten. In the crystal structure, intermolecular O - H center dot center dot center dot O and O - H center dot center dot center dot N hydrogen bonds contribute to the stabilization of the structure.
