TL;DRAbstract
The polymeric structure of the title compound {[Li(C(6)H(3)N(2)O(4))(H(2)O)]·H(2)O}(n), contains two symmetry-independent Li(I) complex units, both having distorted trigonal-bipyramidal coordination environments. The Li(I) ions are bridged by both the N and O atoms of the ligands, generating two symmetry-independent polymeric chains propagating along the b-axis direction. In both ligands, the second carboxyl-ato O atom remains protonated, serving as a donor in a short intra-molecular O-H⋯O hydrogen bond. The coordination of each Li(I) ion is completed by a water O atom. The ribbons are held together by a network of O-H⋯O hydrogen bonds in which the coordinated and uncoordinated water mol-ecules are donors and the carboxyl-ato O atoms act as acceptors.
