Catena-Poly[[di-aqua-bis-(?3-5-carboxyl-ato-1H-pyrazole-3-carb-oxy-lic acid-?(3) O (3):O (3);O (5))dilithium(I)] monohydrate].

ABSTRACT: The basic structural unit of the title polymeric ribbon, {[Li2(C5H3N2O2)2(H2O)2]·H2O} n , is a centrosymmetric dinuclear complex in which the two Li(I) ions are bridged by two carboxyl-ato O atoms, to generate a centrosymmetric Li2O2 core. These are connected into a chain along [01-1] by carboxylic acid-carbonyl-O bonds. The tetra-hedral coordination of the Li(I) cation is completed by an aqua ligand. The carboxylic acid is involved in an intra-ribbon hydrogen bond. A solvate water molecule showing positional (50:50) disorder is observed. Polymeric ribbons along [01-1] are connected by O-H?O, N-H?O and O-H?N hydrogen bonds into a three-dimensional architecture.
