The reactions between oxophilic group 4 metal chlorides, alpha-keto ylides in THF, led to the formation of titanium, zirconium and hafnium edge-shared [M2Cl10](2-) complexes (1a-3f). We describe that the reaction between MCl4 (M = Ti, Zr and Hf) with phosphorus ylides produce edge-shared [M2X10](2-) complexes instead of O-coordination previously reported complexes. Adding dimethyl sulfoxide (DMSO) to these complexes in room temperature crystalline solid [M(DMSO)(8)] center dot 4Cl center dot mH(2)O center dot DMSO] (M = Ti (1g), Zr (2g) and Hf (3g); m = 0-3) together with phosphonium salts in mother liquid were formed. The compounds were characterized by elemental analysis, IR and H-1, C-13 and P-31 NMR spectroscopy.
