Abstract

The solubility of the ternary Zintl phase K₁₂Si_17−xGe_x (x = 5), containing mixed group 14 element clusters, was investigated. Novel dimeric tetrahedral Zintl clusters [(η²-E₄)Zn(η²-E₄)]⁶⁻ with mixed site occupation (E = Si/Ge) were obtained through reaction with (C₆H₆)₂Zn in ammonia solutions and investigated by means of X-ray single crystal diffraction.
