macrometallocycle for 3) was formed by one biscarbene ligand (L1′ for 1, L2 for 2, and L3 for 3) and one Hg(II) ion. Interestingly, the carbonyl group on the 9-position in complex 1 reacted with two acetonitrile molecules in the presence of the strong base KOtBu through losing one molecule of H2O to form L1′. As a result, two –CH2CN units were introduced to anthraquinone, in which the two –CH2CN units
