Aqua(N,N-diethylethylenediamine-kappa N-2,N ')(pyridine-2,6-dicarboxylato-kappa N-3,O,O ')nickel(II) 2.5-hydrate
Özet
In the title compound, [Ni(C7H3NO4)(C6H16N2)(H2O)]center dot 2.5H(2)O, the discrete neutral [Ni(dpc)(dien)(H2O)] ( dien is diethylethylenediamine and dpc is dipicolinate) complex lies on a mirror plane. The Ni-II ion is coordinated by the dpc ligand through the pyridine N atom and one O atom of each carboxylate group, an aqua ligand and two N atoms of the bidentate dien ligand, forming a distorted octahedral geometry. One of the C atoms of the ethylenediamine group is disordered across the mirror plane. The symmetry-independent ethyl group is disordered over two orientations with equal occupancy. The complex molecules are connected via O-H center dot center dot center dot O and N-H center dot center dot center dot O intermolecular hydrogen-bonding interactions.
