Structurally characterized examples of vanadium nitride compounds remain, surprisingly, uncommon.  In our quest to prepare new examples of vanadium nitrides, we have turned our attention to using scorpionates as coligands to support the vanadium nitride moiety.  Scopionates are an important class of tridentate ligands that have been widely used to form a wide array of transition metal complexes.  The phenyltris(methimazolyl)borato ligand (1) is a soft scorpionate, which is capable of binding to metal centers via its three sulfur atoms in a manner making it isoelectronic to a cyclopentadienyl ligand.  Herein, we describe our efforts to prepare vanadium(nitrido) phenyl(methimazolyl)borate complexes.
