An unusual, paramagnetic Sn II ‐centered cage [{[Sn(L)(NMe 2 )Li(thf)][Sn(L)Li(thf) 3 ]Sn} 2 ] (see crystal structure) is generated by the treatment of 2‐aminophenylphosphane (1‐PH 2 ‐2‐NH 2 C 6 H 4 ) with n BuLi and [Sn(NMe 2 ) 2 ]. Remarkable quadruple deprotonation of the ligand results upon use of this mixed system consisting of an alkali‐metal base and a p‐block dimethylamide.
