Abstract:
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 alternatively as either slightly distorted trigonal-bipyramidal or slightly distorted square-pyramidal. The ribbons are inter-connected by a network of O-H⋯O hydrogen bonds.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than...
