transformed in the reversible reaction CO + H(2)O right harpoon over left harpoon CO(2) + 2H(+) + 2e(-). A similar structure has been sought in this work. Mononuclear planar Ni(II) complexes [Ni(pyN(2)(Me2))L](1-) (pyN(2)(Me2) = bis(2,6-dimethylphenyl)-2,6-pyridinedicarboxamidate(2-)) derivedfrom a NNN pincer ligand have been prepared including L = OH(-) (1) and CN(-) (7). Complex 1 reacts with ethyl
