A reinterpretation of the crystal structures of the p-, m-, and o-xylene and carbon disulphide clathrates of tetrakis(4-ethylpyridine)di-isothiocyanato-nickel(II)

Abstract

The crystal structures of the clathrates of [Ni(NCS)₂(4Et-py)₄](4Et-py = 4-ethylpyridine) with p-, m-, and o-xylene and carbon disulphide, reported previously in space group P, have been shown to be more appropriately refined in the tetragonal space group l4₁/a(no. 88). Chemically there is no change in the structures.
