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 [Si7.5(1)Ge 1.5(1)]4- and [Si7.8(1)Ge1.2(1)] 4- as soluble ions opens new synthetic routes for mixed metal semiconductors (see figure).
