01 - 023Oxidative Coupling of Deltahedral [Ge9]4− Zintl Ions. — Thecompound (II) containing the dimeric [(Ge9)2]6− anion is obtained from aformal oxidative coupling reaction (oxidant unknown, probably traces of wateror oxygen). The dimer consists of two identical Ge9 clusters connected via anexo-bond between two vertices. The geometry of the Ge9 cluster is very close tothe classical monocapped square antiprism that is expected for nido deltahedralclusters of nine atoms. (II) crystallizes in the triclinic space group P1 withZ = 1, as determined by single crystal XRD. — (XU, LI; SEVOV, SLAVI C.;J. Am. Chem. Soc. 121 (1999) 39, 9245-9246; Dep. Chem.
