2-aqua-diaquabis(4-pyridazine-3,6-dicarboxylato)tetralithium] monohydrate]Abstract: In the polymeric structure of the title compound {[Li2(C6H2N2O4)2Li(H2O)2Li(H2O)]·H2O}n, the coordination of two independent LiI ions is distorted trigonal-bipyramidal and that of the other two independent LiI ions is distorted tetrahedral. The former two LiI ions are bridged by hetero-ring N atoms of two independent pyridazine-3,6-dicarboxylate ligands, making a dimeric moiety. The carboxylato-O atoms of both bidentate ligands bridge the dimers to adjacent independent aqua-coordinated LiI ions, forming molecular ribbons. The latter are bridged by ligand carboxylato and aqua O atoms, forming molecular layers parallel to (100) which are held together by an extended system of O-H
O hydrogen bonds.
