Metal-involving halogen bonding was detected in a series of associates of CHI3 with trans-[PtX2(NCNAlk2)2] (X = Cl, Br). The HI2C–I⋯η1(Pt) halogen bonding and the bifurcated HI2C–I⋯η2(Pt–Cl) halogen bonding – the latter undergoes the thermally induced reversible HI2C–I⋯η2(Pt–Cl) ⇄ HI2C–I⋯η1(Pt) transformation – were observed and confirmed theoretically.
