The inorganic–organic hybrid material triethyl­enetetra­mmonium hexa­chlorido­rhodate(III) chloride

Single crystals of the new title compound [systematic name: 1,4,7,10-tetra­zoniadecane hexa­chloridorhodate(III) chloride], [H(3)N(CH(2))(2)NH(2)(CH(2))(2)NH(2)(CH(2))(2)NH(3)][RhCl(6)]Cl, were obtained from the corresponding amine and rhodium trichloride in hydro­chloric acid solution by slow crystallization under diffusion-controlled conditions at room temperature. Its solid-state structure is defined by a three-dimensional framework of numerous electrostatic-supported N—H⋯Cl hydrogen bonds between the ionic components of the compound. Within this framework, layered arrangements of the complex ions on one hand and of the protonated amines and chloride ions on the other hand, can be recognized. The octahedral hexa­chloridorhodate(III) anion resides on a [Image: see text] symmetry site, while the triethyl­enetetra­mmonium cation and the chloride ion both reside on twofold axes.
