ResumoCompounds containing magnesium chloride, an ester or an ether, and a tetrachloride of titanium, zirconium or tin have been obtained as MgCl2·MCl4·4L (where M = Ti, Zr or Sn, L = CH3COOC2H5 or tetrahydrofuran; M = Ti, L = HCOOC2H5), MgCl2·TiCl4·2CH3COOC2H5·2L (L = HCOOC2H5 or C6H5COOC2H5), MgCl2·TiCl4·2CH3COOC2H5, and (MgCl2)3·TiCl4·(SnCl4)2·12CH3COOC2H5. The solution properties of several of these species have been studied through ligand displacement reactions using 1H n.m.r. spectroscopy, and the stabilities of some metal chloride/ester (metal = Mg or Ti) adducts have been determined.
