Novel magnesium bis(diphenylphosphorano)methaniide complexes have been synthesized and characterized. Reaction of [Ph2PCH2PPh2] with sulphur afforded the ligand [CH2(PPh2=S)2] (1). Treatment of 1 with Mg(nBu)2 gave the first example of magnesium bis(diphenylthiophosphorano)methaniide complex [(PPh2...
