Crystal structure of chlorido{tris[2-(isopropylsulfanyl)phenyl]phosphane-κ4P,S,S′,S′′}nickel(II) trifluoromethanesulfonate

Abstract

The complex cation of the title compound, [NiCl{P(C6H4-2-S-i-Pr)3}](CF3SO3), has a slightly distorted trigonal–bipyramidal coordination geometry in which three S atoms are located in the equatorial plane, and one P and one Cl atom in the apical positions. In the cation, there are two intramolecular C—H...S hydrogen bonds. In the crystal, there are some intermolecular C—H...O and C—H...F hydrogen bonds formed between the cation and the anion. The trifluoromethanesulfonate anion and one of the methyl groups are both disordered over two sets of sites with occupancies of 0.629 (17):0.371 (17) and 0.786 (14):0.214 (14), respectively.
