Co-assembly of a three-dimensional open framework sulfide with a novel linkage between an oxygen-encapsulated T3 cluster and a supertetrahedral T2 cluster.

Solvothermal reactions of S, Ga and Sn using cis-2,6-dimethylmorpholine (DMMP) as an organic template, in the presence of a trace amount of H2O at 180 °C, generated microporous [C6H14NO]14.4[Ga6.40Sn21.60S52O8] material composed of hybrid T2 and T3 supertetrahedral clusters with a PtS type topology.
