An n.m.r. study of the arachno-[B10H12PPh2]– anion: and interesting arachno→arachno topological transition induced by deprotonation
Abstract
The compound [B10H13PPh2]is remarkably acidic; n.m.r. studies now show that its conjugate base [B10H12PPh2]– derives its stability from an arachno-decaboranyl cluster structure with, uniquely, a bridging {Ph2P} moiety between the B(6) and B(9) positions.
