In the presence of bis[bis-(trimethylsilyl)amino]stannylene hetero-bi-metallic pentakis(THF)dicalcium-tin(II)-bis(tri-iso-propylsilylphosphanide)-bis(tri-iso-propylsilylphosphandiide) 6 can be isolated; in this derivative the calcium atoms are sixfold, the phosphorus atoms quadruple and the tin atoms threefold coordinated (triclinic, , a = 1654.4(1), b = 2137.3(2), c = 2170.6(2) pm, α= 82.285(7), β
