Abstract

The synthesis and crystal structure of four gallium sulphide open frameworks, built from supertetrahedral clusters, are described. The structures of [C4 NH12]6 [Ga10 S18] (1) and [C4 NH12]12 [Ga20 S35.5 (S3)0.5 O] (2) contain supertetrahedral T3 clusters, while in the isostructural compounds [C4 NH12]16 [Ga10 S18 M4 Ga16 S33] (M = Co (3), Zn (4)), T3 and T4 clusters alternate. These materials exhibit three-dimensional frameworks, with topologies consisting of two interpenetrating diamond lattices, and contain over 50% of solvent accessible void space. UV-Vis diffuse reflectance measurements indicate that these compounds are semiconducting, with band gaps over the range 3.4-4.1 eV. © 2006 Elsevier Ltd. All rights reserved.
