چکیده
The asymmetric unit of the title compound, [Li(4)(C(5)H(3)N(2)O(2))(2)(H(2)O)(5)]Cl(2), contains two Li(I) cations, one with a distorted trigonal-bipyramidal and the other with a distorted tetra-hedral coordination geometry. Two symmetry-related asymmetric units constitute a building block of the structure, in which both ligand carboxyl-ate O atoms are bidentate and bridge the metal ions, forming a divalent cation. Charge balance is maintained by two chloride anions. The building blocks, bridged by Li(I) cations, form cationic ribbons with chloride anions in the space between them. The ribbons propagate in [010] and are held together by a network of weak O-H⋯O hydrogen bonds which operate in the space between adjacent ribbons.

In the polymeric structure of the title compound {[Li(2)(C(6)H(2)N(2)O(4))(2)Li(H(2)O)(2)Li(H(2)O)]·H(2)O}(n), the coordination of two independent Li(I) ions is distorted trigonal-bipyramidal and that of the other two independent Li(I) ions is distorted tetra-hedral. The former two Li(I) ions are bridged by hetero-ring N atoms of two independent pyridazine-3,6-dicarboxyl-ate ligands, making a d...
