چکیده
The crystal structure of the title compound, {[Zn(C(6)H(3)N(2)O(4))(H(2)O)(2)]NO(3)}(n), is built of zigzag cationic chains propagating in [010] with nitrate anions located in the space between the chains. The Zn(II) ion is coordinated by N and O atoms of two symmetry-related ligands in equatorial sites, and by two water O atoms at the axial sites of a distorted octa-hedron. One carboxyl-ate group of the ligand remains protonated, serving as a donor in a short intra-molecular O-H⋯O hydrogen bond. The coordinated water mol-ecules are donors and the nitrate O atoms act as acceptors in a network of O-H⋯O hydrogen bonds.

The title compound, {[Li(C5H3N2O2)(H2O)]·0.5H2O} n , comprises four symmetry-independent Li(C5H3N2O2)(H2O) units which form mol-ecular ribbons running along the c-axis direction. Within each ribbon, the ligand mol-ecule, acting in a μ2-mode, bridges two adjacent Li(+) cations using both of its N,O-bonding sites. The coordination environment of each of the four Li(+) cations can be described alt...
