Carboranylamidinates

Carboranylamidinate anions are readily accessible via addition of N,N′-dialkylcarbodiimides to lithio-ortho-carborane. They represent a novel difunctional boron-rich ligand system for main group and transition elements (Li, Sn, Cr). Initial structural investigations revealed an unexpected N,C-coordination mode instead of N,N′-chelation.
