Sulphide and selenide nitrosyl complexes of ruthenium

Abstract

Complexes of the type [Ru(NO)X₃L₂] have been isolated where X = Cl, Br and L = R₂S and PhRS (R = Me, Et, Pr) and Et₂Se and PhEtSe. The complexes, which have the ligands L trans to each other, have been studied by ¹H, ¹³C N.M.R., low-frequency infrared and electronic spectroscopy. Low-temperature ¹H N.M.R. investigations were of assistance in determining the structure of the complexes.
