A singular feature of the catalytic C-cluster of CO dehydrogenase is a sulfide-bridged Ni···Fe locus where substrate is bound and transformed in the reversible reaction CO + H2O â?CO2 + 2H+ + 2e–. A similar structure was sought. Mononuclear planar NiII complexes [Ni(pyN2Me2)L]1- (pyN2Me2 = bis(2,6-dimethylphenyl)-2,6-pyridinedicarboxamidate(2-)) derived from a NNN pincer ligand were prepared including L = OH– (1) and CN– (7). Complex 1 reacts with Et formate and CO2 to form unidentate L = HCO2– (5) and HCO3– (6) products. A binucleating macrocycle was prepared which specifically binds NiII at a NNN pincer site and five-coordinate FeII at a triamine site. The NiII macrocycle forms [Ni(OH)(pyN2dienMe3)L]1- (14) and [Ni(CN)(pyN2dienMe3)L]1-complexes (15) analogous to 1 and 7. Reaction of 14 with FeCl2 alone and with Et formate and 15 with FeCl2 affords mols. with the NiII-L-FeII bridge unit in [Ni(L)FeCl(âpyN2dienMe3)]1- (âpyN2dienMe3 = I) in which L = μ2:η1-OH– (17) and μ2:η2-HCO2– (18) and -CN– (19). All bridges are nonlinear (17, 140.0°; 18, M-O-C 135.9° (Ni), 120.2° (Fe); 19, Ni-C-N 170.3°, Fe-N-C 141.8°) with Ni···Fe separations of 3.7-4.8 à . The NiIIFeII complexes, lacking appropriate Ni-Fe-S cluster structures, are not site analogs, but their synthesis and reactivity provide the 1st demonstration that mol. NiII···FeII sites and bridges can be attained, a necessity in the biomimetic chem. of C-clusters.
