The structure of the arachno-[B10H13CN]2– anion; an example of endo substitution in the decaborane(14) framework
Abstract
The cyano group in [B10H13CN]2– occupies an endo-position with respect to the cage in both solution (n.m.r.) and solid (X-ray crystallography) states, indicating a general pathway for the formation of heteroboranes.
