Synthesis and crystal structure of tetraquaorotatonickel(II) monohydrate
Özet
The title compound, tetraquaorotatonickel(II) monohydrate, C5H12N2O9Ni, crystallizes in the monoclinic space group P1 with the following unit-cell parameters: a = 7.2282(4)Å, b = 8.2959(4)Å, c = 10.0611(5)Å, ? = 80.115(4)°, ? = 70.479(4)°, ? = 65.779(4)° and Z = 2. The NiII ion is coordinated by a deprotonated N atom and the carboxylate O atom of the orotate ligand and four aqua ligands in a distorted octahedral geometry. Intermolecular N-H·O and O-H·O hydrogen bonds produce R22(8), R22(12), R22(16), R32(8), R43(8) and R44(12) rings, which lead to a one-dimensional polymeric chains. An extensive three-dimensional network of N-H···O and O-H···O hydrogen bonds, ?-? and N-H···? interactions are responsible for crystal stabilization. 2008 © The Japan Society for Analytical Chemistry.
