Synthesis and Structural Characterization of Amidine, Amide, Urea and Isocyanate Derivatives of the Amino- closo -dodecaborate Anion [B 12 H 11 NH₃]

The synthesis and structural characterization of new derivatives of [B H ] is of fundamental interest and is expected to allow for extended applications. Herein we report on the synthesis of a series of amidine, amide, urea and isocyanate derivatives based on the amino- -dodecaborate anion [B H NH₃] . Their structures have been confirmed by spectroscopic methods, and nine crystal structures are presented.
