Uncoordinated inorganic salt in 1D chain structure:formation of a novel supermolecule [HgBr_2(ptz)]_2 centre dot HgBr_2 (ptz=phenothiazine)

摘要

A novel supermolecule [HgBr_2(ptz)]_2 centre dot HgBr_2 (ptz=phenothiazine) with uncoordinated inorganic salt HgBr_2 presented in a 1D chain was prepared.The bulky ligand phenothiazine has unusual coordination mode with large steric inhibition perpendicular to the chain direction.The uncoordinated HgBr_2 molecule was stabilized by multiple weak Hg…Br interactions and the whole structure was also stabilized by strong pi-pi interactions and N-H…Br hydrogen bonds to form 2D network.
