![]() ![]() This instability is most likely caused by mismatch between the size of Mn(II) and the coordination cavity of the biscapped tris(dioxime) ligands. It was found that the biscapped Mn(II) complexes are not stable in the presence of water, and readily hydrolyze to form the monocapped cationic complexes +. All tris(dioxime) Mn(II) complexes have been characterized by elemental analysis, IR, UV/vis, cyclic voltammetry, ESI-MS, and in cases of OH♼HCl 3 and by X-ray crystallography. ![]() ![]() This report describes the synthesis and characterization of a series of novel biscapped and monocapped tris(dioxime) Mn(II) complexes: and + (dioxime = cyclohexanedione dioxime (CDOH 2) and 1,2-dimethylglyoxyl dioxime (DMGH 2) R = Me, n-Bu, and Ph).
