Chlorido(4′-chloro-2,2′:6′,2′′-terpyridine-κ3N,N′,N′′)(trifluoromethanesulfonato-κO)zinc(II) acetonitrile monosolvate

Abstract

In the title complex, [Zn(CF3O3S)Cl(C15H10ClN3)]·CH3CN, the zinc(II) core is fivefold coordinated by one chloride, one trifluoromethanesulfonate 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-chloroterpyridine 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 trifluoromethanesulfonate ion. A molecule of acetonitrile is also found in the asymmetric unit of the title complex.
