Crystal structure of Li2HPO3,H2O was determined by single-crystal X-Ray diffraction analysis at 173(2) K. It crystallizes in the monoclinic system (P21/c) with the parameters: a = 5.0322(9) angstrom, b = 8.9795(17) angstrom, c = 17.088(4) angstrom, beta = 92.672(16)degrees and Z = 8. The structure was refined to R = 0.0237 and omega R = 0.0650 for 1449 reflexions. The framework of Li2HPO3, H2O can be described as layers perpendicular to the crystallographic c axis. The structure contains two types of Li-tetrahedrons. In one kind each O atom belongs to one HPO3 group, while in the second kind one apex is an O from water. A network of hydrogen bonds interactions insures the connection between the layers.
