Homoatomic nine-atom clusters of the elements Si, Ge, Sn, and Pb represent a fascinating
class of molecules. The Zintl anions [E9] x− occur with different charges x and various …

The challenges associated with synthesizing expanded semiconductor frameworks with
cage-like crystal structures continue to be of interest,. Filled low-density germanium and …

Not only fullerenes but also inorganic cage molecules can be highly spherical aromatic. The
molecular allotropes 1 (E= N, P, As, Sb, Bi) of the Group V elements and a variety of Zintl …

For the first time, a dimer of deltahedral Zintl ions is made. Interest in synthesis, isolation,
and characterization of deltahedral Zintl ions from solutions dates back to the 19th century, 1 …

The title anion was synthesized by oxidation of nido-Ge94-with Ph3P or Ph3As in
ethylenediamine solution. It was structurally characterized in the compound (Rb-2, 2, 2 …

A tetramer of nine-atom deltahedral germanium clusters and charge 8−,[Ge9 Ge9 Ge9 Ge9]
8-, has been characterized as a (Rb-18C6)+ salt (18C6= 18-crown-6 polyether). The clusters …

The closo-[1-M (CO) 3 (η4-E9)] 4-(E= Sn, Pb; M= Mo, W) anions have been obtained by
extracting the binary alloys KSn2. 05 and KPb2. 26 in ethylenediamine (en) in the presence …

A series of different compounds of stoichiometries AI12MIV17 (AI= Na, K, Rb, Cs; MIV= Si,
Ge, Sn) and AI4M9IV (AI= K, Rb; MIV= Pb) were synthesized from the elements and their …

Six new derivatized deltahedral Zintl ions have been synthesized by reactions between the
known Zintl ions Ge9n− with the halides R3EX and/or the corresponding anions R3E− for E …

The title compounds were prepared by direct reactions of the corresponding elements at
high temperature. They are isostructural with each other (monoclinic, P 21/m, Z= 2; …
