          Structural and electronic flexibility in a tripodal ligand platform featuring a secondary coordination sphere.

          Abstract

          The syntheses of M( ii) (M = Mn, Fe, Co) complexes bearing the tris(5-cycloaminoazafulvene-2-methyl)amine (H 3N(afa Cy) 3) ligand in its datively coordinated, tautomeric form is reported. The metal–azafulvene complexes [N(afa Cy) 3M](OTf) 2 are generated in high yields, featuring a secondary coordination sphere composed of amino moieties from the ligand platform. To investigate the ability of the hydrogen bonding network to support hydrogen-bond accepting, coordinating anions, pseudohalide derivatives, [N(afa Cy) 3MX](OTf) (X = NCS , NCO , N 3 ) were synthesized by exposure of [N(afa Cy) 3M](OTf) 2 to an equivalent of the corresponding salt, [( nBu) 4N](X). Structural characterization of the products reveals two isomorphs of the desired species. One complex features a single hydrogen bonding interaction with the pseudohalide, while the second compound has two H-bonds from the secondary coordination sphere to the coordinated anion. These complexes showcase the structural and electron flexibility of the ligand platform, presenting a scaffold capable of accessing a different number of hydrogen bonds for stabilizing a given moiety.
