Halogen bonding between metal centers and halocarbons

Abstract

Metal-involving halogen bonding was detected in a series of associates of CHI3 with trans-[PtX2(NCNAlk2)2] (X = Cl, Br). The HI2C-Iη(1)(Pt) halogen bonding and the bifurcated HI2C-Iη(2)(Pt-Cl) halogen bonding - the latter undergoes the thermally induced reversible HI2C-I∙∙∙η(2)(Pt-Cl) ⇄ HI2C-I∙∙∙η(1)(Pt) transformation - were observed and confirmed theoretically.
