Studies in Werner clathrates. Part 9. Structures with bis(isothiocyanato)-tetrakis(4-phenylpyridine)nickel(II) as host

Abstract

The structures of the Werner clathrates with the host complex [Ni(NCS)₂(4-Phpy)₄](4-Phpy = 4-phenylpyridine) and mixed guests (4-phenylpyridine + dimethyl sulphoxide), (4-phenylpyridine + 2-methoxyethanol), and (phenylacetylene + dimethyl sulphoxide) have been elucidated. The packing of these three complexes has been compared. Trends in the torsion angles of the host molecules of the complexes and of [Ni(NCS)₂(4-Phpy)₄]·m-MeC₆H₄Me are discussed and their importance to the process of clathration highlighted.
