Four quadruply bonded dichromium complexes with mixed-ligand sets, Cr 2(formamidinate)n(acetate)4-n (n = 2-4), were synthesized from reactions of anhydrous Cr2(O2CCH 3)4 and formamidinate anions. The Cr-Cr bond lengths fall in the range for supershort Cr-Cr bonds as they vary from 1.8897(5) A to 2.012(1) A. The distance variation depends on the presence or absence of weak axial interactions. Because formamidinate ligands are less labile than acetate groups, these compounds may be useful building blocks for the construction of neutral supramolecules having dichromium units linked by polydentate dianions.
