The Controlled Oxidative Coupling of G e49 - Zintl Anions to a Linear Trimer
[Ge9=Ge 9=Ge 9]6-. — Compound (IV) crystallizes in the monoclinic space group P21/c
with Z = 4 (single crystal XRD). The neighbored nine-atom clusters in the
[Ge9=Ge9=Ge9]6- anion are connected by two covalent Ge—Ge exo-cluster bonds with
Ge—Ge distances in the range 2.581—2.640 Å. The single crystal structure analysis
shows that, with respect to bond connection and packing style, compound (IV) is quite
different from the previously reported compound
[Rb(2.2.2-crypt)]6[Ge9=Ge9=Ge9]·3en. — (YONG, L.; HOFFMANN, S. D.;
FAESSLER*, T. F.; Z. Anorg. Allg. Chem. 631 (2005) 6-7, 1149-1153; Lehrstuhl
Anorg. Chem., TU Muenchen, D-85747 Garching, Germany; Eng.) — Schramke
