Abstract
The Ru(II)–H2S complexes cis-RuX2(P–N)(PPh3)(SH2) {X = Cl, Br; P–N = [o-(N,N-dimethylamino)phenyl]diphenylphosphine} are characterised crystallographically and by 31P{1H}, 1H and 1H{31P} NMR spectroscopies; the 1H NMR spectra at –50 °C show three-bond coupling of only one H-atom of the coordinated H2S to the P-atom of the P–N ligand, and this represents an extension of the Karplus relationship to vicinal coupling within a P–Ru–S–H system.Keywords
