An entirely new type of chalcogenide cluster and a new structural mechanism for the formation of large semiconducting tetrahedral clusters have been revealed as a result of crystallization of a templated indium sulfide consisting of an unprecedented cluster, In38S65, which is the largest supertetrahedral cluster based on trivalent metal ions. At the core of this cluster is In10S13, which can be considered as a fragment of the NaCl-type lattice. The In10S13 cluster is coupled to four In4S10 supertetrahedral T2 clusters and four In3S3 hexagonal rings to give In38S65, which is also the largest inorganic chalcogenide supertetrahedral cluster, superseding a supertetrahedral T5 cluster with only 35 metal sites.
