The reaction of Sn(NMe2)2 with the primary phosphido alkali metal complex PhPHNa(1:2 equiv, respectively) in the presence of the Lewis base donor PMDETA [(Me2NCH2CH2)2NMe] gives the heterometallic cage [{(PhP-PPh)Sn(
-PPh)}2(Na·PMDETA)4 (1), containingthe novel [(PhP-PPh)Sn(-PPh)]24- tetraanion. The analogous reaction using pyPHLi (py= 2-pyridyl) in THF/toluene as the solvent gives the neutral cage [{Sn(3-Ppy)}3{Sn(3,1-pyP-Ppy)}3] (2), having a unique "stacked" propeller arrangement in the solid state.
