Linkage isomerism in hydride complexes of platinum(II)

Abstract

Complexes of the type trans-[L₂PtHX](L = Ph₃P, Ph₂EtP, Buⁿ₃P, Et₃P, Et₃As and X = NCO, NCS, CN, NCSe) have been prepared. It was found that linkage isomerism was exhibited only by the thiocyanate complexes. The assignment of spectral parameters was not based on the nuclear quadrupole broadening effect of the nitrogen atom since phosphine ligand exchange is known to occur in these complexes. The effects of temperature, solvent, concentration, and the nature of L on the linkage isomer ratio have been studied.
