Notes:
The tetraphenylimidodiphosphinate [N-(P,P-diphenylphosphinoyl)-P,P-diphenylphosphinimidate] ion forms stable bis-chelates with SnII and SnIV. The SnII compound [N(Ph2PO)2]2Sn (3) displays a distorted Ψ-tbp structure in the solid state and is fluxional in solution. The bis(imidodiphosphinato)tin dihalides 6 are cis-structured. A comparison of the X-ray structures of 3 and the diiodide [N(Ph2PO)2]2SnI2 (6c) indicates the presence of a lone-pair stereochemical effect in 3 which is absent in 6c.
