Phosphandiides dilithium

The dilithium phosphandiide dimer 9 is complexed by two molecules of a fluorosilane. The complex crystallizes in the monoclinic space group P2i/n. The framework of the aggregate consists of a cen-... 

In contrast to magnesium phosphandiides, analogous tin(II) derivatives possess more covalent metal-phosphorus bonds. This basic difference is also apparent for dilithium versus dicopper(I) phosphandiides (see Section II and III). It is, therefore, interesting to assess the structural and electronic features of such species in a similar way. To date, only three tin(II) phosphandiide derivatives have been prepared...
