Abstract

Towards silicon microelectronics: Dissolution of the heteroatomic Group 14 element Zintl phase Rb₁₂Si₁₂Ge₅ in liquid ammonia led to the isolation of two [E₉]^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).
