The complexes [Pt(CN)H2X(PEt3)2](X = Cl, Br, or I) have been identified by 1H and 31P n.m.r. spectroscopy at –80 °C as the initial products from the reaction of trans-[Pt(CN)H(PEt3)2] and HX. Similarly, [PtH(PEt3)3]+ and HCl yield [PtClH2(PEt3)3]+. In this case deuterium substitution indicates trans addition, but with the cyanide no distinction of cis or trans addition is possible. The platinum(IV)
