metal-organic compounds
The hydrothermal reaction of Ni(NO3)2·2H2O, KOH and taurine produced the title compound, K[Ni(C2H6NSO3)3]. The NiII atom is chelated by the three taurinate ligands in a deformed octahedral geometry and in a facial manner. Each taurinate ligand bridges two K+ ions via its sulfonate group, forming a three-dimensional framework.
