Pushing the Frontiers of Hard and Soft Scorpionate Chemistry

The preparation and structure of the first scorpionate complex of a group 16 element, [Te(κ2-TmMe)2], is reported. It displays square planar geometry at the Te atom and two distinct ligand conformations. In addition, the first pyrazolylborate complex of a group 15 element, [Bi(Tp)2(pzH)Cl], has been synthesized and characterized.
