The reaction of 2,3,5,6‐tetracyanopyridine (TCNPy) and Cr(C 6 H 6 ) 2 forms diamagnetic σ‐[TCNPy] 2 2− possessing a 1.572(3) Å intrafragment sp 3 –sp 3 bond. This is in contrast to the structurally related 1,2,4,5‐tetracyanobenzene and 1,2,4,5‐tetracyanopyrazine that form π‐dimer dianions possessing long, multicenter bonds.
