Synthesis of binucleating macrocycles and their nickel(II) hydroxo- and cyano-bridged complexes with divalent ions: Anatomical variation of ligand features

The planar NNN-pincer complexes [MII(pyN2 Me2)(OH)]1- (MII = Ni, Cu) fix CO2 in η1-OCO2H complexes; results for the copper system are described. MnII, FeII, CoII, and Zn II behave differently, forming [MII(pyN2 Me2)2]2- with N4O2 coordination. Incorporation of the NiII pincer into binucleating macrocycle 2 containing a triamino MII locus connected by two 1,3-biphenylene groups affords proximal NiII and MII sites for investigation of the synthesis, structure, and reactivity of Ni-X-M bridge units. This ligand structure is taken as a reference for variations in M II atoms and binding sites and bridges X = OH- and CN - to produce additional members of the macrocyclic family with improved properties. Macrocycle 2 with a 22-membered ring is shown to bind MII = Mn, Fe, and Cu with hydroxo bridges. Introduction of the 4-BuiO group (macrocycle 3) improves the solubility of neutral complexes such as those with NiII-OH-CuII and Ni II-CN-FeII bridges. Syntheses of macrocycle 5 with a 7-Me-[12]aneSN3 and macrocycle 6 with a 1,8-Me2-[14] aneN4 MII binding site are described together with hydoxo-bridged Ni/Cu and cyano-bridged Ni/Fe complexes. This work was motivated by the presence of a Ni...(HO)-Fe bridge grouping in a reactive state of carbon monoxide dehydrogenase. Attempted decrease in Ni-(OH)-M distances (3.70-3.87 A) to smaller values observed in the enzyme by use of macrocycle 4 having 1,2-biphenylene connectors led to a mononuclear octahedral NiII complex. Bridge structural units are summarized, and the structures of 14 macrocyclic complexes including 8 with bridges are described.
