Towards silicon microelectronics : Dissolution of the heteroatomic Group 14 element Zintl phase Rb 12 Si 12 Ge 5 in liquid ammonia led to the isolation of two [E 9 ] 4− clusters with Si and Ge mixed site occupation. The existence of [Si 7.5(1) Ge 1.5(1) ] 4− and [Si 7.8(1) Ge 1.2(1) ] 4− as soluble ions opens new synthetic routes for mixed metal semiconductors (see figure).
