119 Sn Fourier transform n.m.r. studies of [Ru(SnCl3)6]4–have revealed its stereochemical rigidity and a large two-bond tin–tin coupling constant, 2J(119Sn–117Sn), for the trans-disposed trichlorostannato ligands, the reduced value of which, 2K(SnSn)trans,806.0 × 1021 cm–3, is the largest among analogous transition metal–tin complexes.
