  名称：

  A second polymorph of bis(dimethylphosphino)dimethylphosphonium trifluoromethanesulfonate

  摘要：

  The title compound, C6H18P3+center dot CF3SO3-, crystallizes in two polymorphic forms in the space groups P2(1)/c and Pnma. In the orthorhombic form, the two crystallographically independent molecular units lie across a crystallographic mirror plane. The compound lacks traditional hydrogen-bond donors and, hence, is held together by weak C-H center dot center dot center dot O and C-H center dot center dot center dot F interactions, forming layers. The second polymorph was obtained as a by-product from the reaction of 1,3-bis(2,6-dimethylphenyl)-2,4-ditriato-1,3,2,4-diazadiphosphetidine with tetramethyldiphosphine.
