Structural features of a new [Fe(nicotinamide)(2)(H2O)(4)]center dot[Fe(H2O)(6)]center dot (SO4)(2)center dot 2H(2)O complex
Özet
A new nicotinamide complex of Fe(H) cation was prepared by reaction between ferrous sulfate and nicotinamide in aqueous solution. The complex was characterized on the basis of elemental analysis, FT IR and UV-VIS spectroscopy, electrochemistry (cyclic voltammetry) and X-ray crystallography. The complex consists of the molecular composition of [Fe(nicotinamide)(2)(H2O)(4)]center dot [Fe(H2O)(6)]center dot(SO4)(2)center dot 2H(2)O. The complex crystallizes in the monoclinic space group P2(1)/c [a = 12.862(3), b = 7.110(3), c = 16.382(3) angstrom; beta = 95.79(2)degrees]. It has been proven that nicotinamide is coordinated to Fe(H) through the nitrogen atom of its heterocyclic ring.
