摘要：
Treatment of (ArECl)-E-# (Ar-# = C6H3-2,6-Mes(2); E = Ge or Sn) with 1 equiv of the reducing agent KC8 or 'GaI' led to the isolation and characterization of the two new main group clusters Ge-2{Sn(X)Ar-#}(3), 1, and Ga-2{Ge(X)Ar-#}(3), 2 (X = Cl or Cl/I), which have trigonal bypyramidal Ge2Sn3 or Ga2Ge3 frameworks. Cluster 1 is a singlet biradicaloid, whereas 2 is a very rare heavier group 13/14 element cluster, and the first with a Ga/Ge framework.
