Bis(hydrazin-1-ium) bis-(μ(2)-pyridazine-3,6-dicarboxyl-ato)bis-(aqua-lithiate) octa-aqua-bis-(μ(3)-pyridazine-3,6-dicarboxyl-ato)tetra-lithium.

ABSTRACT: The unit cell of the title compound, (N(2)H(5))(2)[Li(2)(C(6)H(2)N(2)O(4))(2)(H(2)O)(2)]·[Li(4)(C(6)H(2)N(2)O(4))(2)(H(2)O)(8)], comprises two centrosymmetric complexes, one double negatively charged and one neutral, and two mono-protonated hydrazine cations. The anionic complex molecule is a dimer, built of a pair of symmetry-related pyridazine-3,6-dicarboxyl-ate ligands and a pair of Li(I) ions, each coordinated by two N,O-chelating sites donated by a ligand mol-ecule and an aqua O atom at the apical position. The penta-coordination around the Li(I) ions is partway between a trigonal-bipyramidal and a square-pyramidal arrangement. The two carb-oxy-lic acid groups of the ligand are deprotonated and one carboxyl-ate O atom of each group is not involved in the coordination, and this applies
