Abstract

The reaction of Rb₄Sn₄ with ZnPh₂ in liquid ammonia in the presence of [2.2.2]-cryptand yielded crystals of Rb₆[(η²-Sn₄)Zn(η³-Sn₄)]·5NH₃, which could be characterized by single crystal X-ray diffraction. This is the first example of a successful solution reaction of the highly charged tetrahedral Sn₄⁴⁻ anions. The homoleptic [E₄ZnE₄]⁶⁻ complex (E = tetrel element) was previously known only for E [double bond, length as m-dash] Ge and Si/Ge.
