What is Coordination chemistry of heterocycle-functionalized diazamesocycles: tuning the productive NiII complexes through altering the pendants of ligands about?
In order to further understand the coordination chemistry of diazamesocyclic systems, a series of mononuclear Ni II complexes with 1,4-diazacycloheptane (DACH) functionalized by additional imidazole or pyridine donor pendants, including 5), where , and L 3 = 1,4-bis-(imidazol-4-yl-methyl)-1,4-diazacycloheptane, have been prepared and characterized. A detailed study on the solid structures and solution spectra of these complexes indicates that tetradentate ligands L 1 , L 2 and L 3 would lead to new Ni II complexes with different coordination environments in the solid states and solution. The N-methyl substituted imidazole functionalized ligand L 1 forms green compound 2 and yellow product 1; while the pyridine functionalized ligand L 2 affords red product 4 and green complex 3; the ligand L 3 results in only one stable mononuclear Ni II product 5. The solution behaviors of these interesting compounds were also investigated by UV-Vis technique.
