Arrays of chiral nanotubes and a layered coordination polymer containing gallium-sulfide supertetrahedral clusters.

Organically functionalised supertetrahedral clusters: Two novel coordination polymers, consisting of chiral helical nanotubes and of composite layers, have been obtained by linkage of gallium-sulfide supertetrahedral clusters and dipyridyl ligands (see picture).

Zero-dimensional units of ligand-bridged gallium-sulfide supertetrahedra.

The synthesis and characterization of the first anions containing two gallium-sulfide supertetrahedra linked via an organic moiety are described.

Gallium-sulfide supertetrahedral clusters as building blocks of covalent organic-inorganic networks.

The synthesis and characterization of novel covalent organic-inorganic architectures containing organically functionalized supertetrahedra is described. The structures of these unique materials consist of one-dimensional zigzag chains or of honeycomb-type layers, in which gallium-sulfide supertetrahedral clusters and dipyridyl ligands alternate.

[Ga10S16(NC7H9)(4)](2-): a hybrid supertetrahedral nanocluster.

The synthesis and characterisation of a hybrid supertetrahedral nanocluster, [Ga10S16(NC7H9)(4)](2-), in which the terminal S(2-) anions have been replaced by covalently bonded amine molecules, is described.
