Chlorido-(4'-chloro-2,2':6',2''-terpyridine-κ ,','')(tri-fluoro-methane-sulfonato-κ)zinc(II) aceto-nitrile monosolvate.

In the title complex, [Zn(CFOS)Cl(CHClN)]·CHCN, the zinc(II) core is fivefold coordinated by one chloride, one tri-fluoro-methane-sulfonate O atom and three terpyridine N atoms in a slightly distorted square-pyramidal geometry. The structure provides a distinct example amongst other zinc(II) 4-chloro-terpyridine complexes because of the unusual planarity of the coordinated chloride, the short length of the Zn-N bond opposite to the chloride ligand [1.9572 (15) Å], and the presence of an elongated Zn-O bond [2.3911 (14) Å] in the coordinated tri-fluoro-methane-sulfonate ion. A molecule of acetonitrile is also found in the asymmetric unit of the title complex.
