A two-dimensional layered cadmium sulfide superlattice constructed from capped-supertetrahedral C1 clusters

摘要

A new two-dimensional layered cadmium sulfide framework MSF-5 based on a capped-supertetrahedral C1 cluster [Cd_(17)S4(SPhMe-4)_(27)(SH)]~(2-) has been synthesized. MSF-5 possesses a 3-connected 6~3-hcb net, in which each C1 cluster connects through Cd-S(PhMe-4)-Cd covalent bonds with three neighboring clusters to form a 2D superlattice with 6-membered rings. The 2D sheets stack over each other to form a 3D network. MSF-5 has high thermal stability and is a wide-gap semiconductor.
