The platinum diboran(4)­yl complexes 13 have been prepared by the selective oxidative addition of one B–Hal bond in aryl-substituted diboranes(4) Hal2B2Ar2 (Hal = Cl, Ar = mes, dur; Hal = I, Ar = mes). Because of the electron deficiency of the remote B2 atom, all species show a rare dative Pt–B bonding interaction, whose magnitude is strongly dependent on the nature of the halide substituent.
