The “counterion” BPh 4 −functions a sandwich ligand in the niobium( I ) complex 1 . This is confirmed by the X‐ray structure analysis of 1 a. The BPh 4 −complexes 1 are the first in which two of the four phenyl rings of the tetraphenylborate bind to one metal center. Such complexes could be important as model compounds for catalytic processes.
