Reaction of (1) with ethylenediamine (en) in ethanol (1 : 1 molar ratio) gives (3), shown by i.r., (1)H and (31)P-<(1)H> n.m.r. studies to contain trans-S-bonded -SCOPh and cis-PMe2Ph groups.Reaction of (1) with 2,2'-bipyridyl (bipy) or 1,10-phenanthroline (phen) also gives the six-co-ordinate complexes but spectroscopic and X-ray analyses (for N-N = phen) reveal that the major product has the cis,cis,cis configuration (4).The crystals are monoclinic, space group P2₁/c, with a = 15.710(1), b = 13.729(2), c = 17.482(2) Angstroem, and β = 90.79(1).A minor product shown by X-ray analysis to bis cis,cis,trans- (5) is also formed.The crystals are monoclinic, space group P2₁/c, with a = 16.896(4), b = 10.754(2), c = 21.332(2) Angstroem, and β = 94.92(1).
