A facile approach to hexanary chalcogenoborate featuring a 3-D chiral honeycomb-like open-framework constructed from rare-earth consolidating thiogallate-closo-dodecaborate

摘要

A novel chiral open-framework structural hexanary chalcogenoborate, (K_3I)[SmB_(12)(GaS_4)_3] (1), was obtained by a facile approach using boron as the reducing reagent; it shows weak SHG-activity and is transparent in the mid-IR region.
