Abstract Two manganese(III)‐dicyanamide compounds, [Mn(5‐Brsalen)(dca)] · CH 3 OH ( 1 ) and [Mn(3‐Meosalphen)(dca)(H 2 O)] ( 2 ) (dca = dicyanamide anion, [N(CN) 2 ] – ), were synthesized and characterized by elemental analysis, IR spectroscopy, single‐crystal X‐ray structure analysis, and cyclic voltammetry. The structure of complex 1 is an infinite zigzag chain of hexacoordinate Mn III ions, in which the adjacent manganese atoms are connected by dca in μ 1,5 ‐bridging mode. The molecular structure of complex 2 consists of a hexacoordinate Mn III atom, which generates a slightly distorted octahedral arrangement, and a dimer structure is formed by intermolecular hydrogen bonding interactions. The electrochemical properties of the two complexes were measured by cyclic voltammetry.
