Bottom Line: The two Na(+) cations exhibit distorted octa-hedral NaCl(2)O(4) coordination polyhedra, each consisting of two deprotonated O atoms of the bis-phospho-nate anion, of two water mol-ecules and of two chloride anions.Strong O-H⋯O hydrogen bonds between the -OH group and one of the free O atoms of the bis-phospho-nate anion connect adjacent layers along [100], supported by N-H⋯Cl inter-actions.Intra-layer O-H⋯O and N-H⋯O hydrogen bonds are also observed.

ABSTRACT
The title compound, [Na(2)(C(2)H(8)NO(6)P(2))Cl(H(2)O)(2)](n), has a polymeric two-dimensional structure extending parallel to (001). The asymmetric unit contains two Na(+) cations located on a centre of symmetry and on a mirror plane, respectively, one half of a bis-phospho-nate anion (the entire anion is completed by mirror symmetry), one chloride anion on a mirror plane and one water mol-ecule in general positions. The two Na(+) cations exhibit distorted octa-hedral NaCl(2)O(4) coordination polyhedra, each consisting of two deprotonated O atoms of the bis-phospho-nate anion, of two water mol-ecules and of two chloride anions. Strong O-H⋯O hydrogen bonds between the -OH group and one of the free O atoms of the bis-phospho-nate anion connect adjacent layers along [100], supported by N-H⋯Cl inter-actions. Intra-layer O-H⋯O and N-H⋯O hydrogen bonds are also observed.
