Acidity/hydridicity evaluation of Sb-H bonds and formation of a new Group 15 metal cluster topology

Abstract

We report first quantitative estimates for the pKa and hydride donor ability of a fifth-row E-H bond besides Sn-H bonds. A new D2d-symmetric cluster type for M8 species (M = pnictogen) is shown, along with the first amido-stibanide. Sterically determined deprotontion and redox outcomes are demonstrated.
