Abstract

In this review, we report isolation of unstable tri-sulfur, S3, in a porous coordination network which is used as a crystalline molecular flask. The ozone-like structure of S3 in a pore was determined by ab initio X-ray powder diffraction analysis. The S3 in the pore was interacted with iodine which faces to the pore of the network. The S3 in the network was quite stable unlike unstable gaseous S3 molecule because of the S-I interaction in the pore. Furthermore, the S3 in the network could be transformed to S6 by mechanical grinding or heating in the presence of NH4Cl. We will introduce new chemistry of small sulfur based on crystal structure.
