Synthesis, crystal structure and luminescence properties of one inorganic–organic hybrid compound [FTMA]2[Co(NCS)4] (FTMA = ferrocenylmethyltrimethylammonium cation)

A new inorganic–organic hybrid compound [FTMA]2[Co(NCS)4] (FTMA = ferrocenylmethyltrimethylammonium cation) has been synthesized and characterized by IR, UV, elemental analysis and X-ray crystallography. Co(II) atom has a distorted tetrahedral environment with four N atoms of four NCS− anions. In the solid state there are C–H⋯π interactions between adjacent ferrocenyl cations, which generate one-dimensional (1-D) supramolecular chain, and C–H⋯S hydrogen bonds between [FTMA]+ cations and cobalt thiocyanate anions. The title compound shows strong purple fluorescence emission in the solid state at room temperature.
