title: Crystal structure of catena-poly[[[aqua-lithium(I)]-μ-pyrimidine-2-carboxyl-ato-κ(4) N (1),O (2):N (3),O (2')] hemihydrate].
abstract: The title compound, {[Li(C5H3N2O2)(H2O)]·0.5H2O} n , comprises four symmetry-independent Li(C5H3N2O2)(H2O) units which form mol-ecular ribbons running along the c-axis direction. Within each ribbon, the ligand mol-ecule, acting in a μ2-mode, bridges two adjacent Li(+) cations using both of its N,O-bonding sites. The coordination environment of each of the four Li(+) cations can be described alternatively as either slightly distorted trigonal-bipyramidal or slightly distorted square-pyramidal. The ribbons are inter-connected by a network of O-H⋯O hydrogen bonds.
