o ‐Dilithiobenzene adds hexacarbonylchromium, ‐molybdenum or tungsten; alkylation of the intermediates leads to the 1,4‐chelated biscarbene complexes (1) – (3) , which are stable as permanganate‐colored to black leaflets at room temperature. Spectroscopic studies show that these compounds have a distorted octahedral structure.
