Structural Investigation of a Fully Ordered closo-Ge-9(2-) Cluster in the Compound [K+(2,2,2-crypt)](2)Ge-9(2-)
(2011) In European Journal of Inorganic Chemistry p.3999-4005- Abstract
- [K+(2,2,2-crypt)] Ge-2(9)2- containing the deltahedral Zintl anion Ge-9(2-) has been isolated from a solution of K4Ge9 in ethylenediamine in the presence of 2,2,2-crypt, intended as an intermediate in mixed-cluster synthesis. The subsequent crystallographic characterisation shows the closo-Ge-9(2-) cluster unit to be tricapped trigonal-prismatic with a symmetry very close to D-3h. Each Ge-9(2-) unit is surrounded by two 2,2,2-crypt units, each with a chelated K+ cation, viz. [K+(2,2,2-crypt)]. The structure characterisation of this ordered Ge-9(2-) cluster is surprisingly enough the first one reported. A chemical bonding analysis reveals two local minima of D-3h symmetry, with that of lowest energy being highly similar to that resulting... (More)

A chemical bonding analysis reveals two local minima of D-3h symmetry, with that of lowest energy being highly similar to that resulting from the crystallographic analysis of low-temperature data. The cluster interaction scheme is based on highly delocalised bonding. (Less)
