Electrochemical synthesis of manganese(II) complexes of pyrimidine-2-thiones: The crystal structures of bis-4,6-dimethylpyrimidyl-2,2′-disulphide and 1,10-phenanthroline-bis (4,6-dimethylpyrimidine-2-thiolato)manganese(II)
摘要:
The electrochemical oxidation of anodic manganese in an acetonitrile solution of pyrimidine-2-thione (pymtH) or 4,6-dimethylpyrimidine-2-thione (4,6-Me(2)pymtH) and nitrogen donor bidentate ligands such as 1,10-phenanthroline (phen) or 2,2'-bipyridine (bipy), yielded mixed complexes [Mn(pymt)(2)phen], [Mn(4,6-Me(2)pymt)(2)phen] and [Mn(4,6Me(2)pymt)(2)bipy]. The crystal structures of bis-4,6-dimethylpyrimidyl-2-2'disulphide and 1,10-phenanthroline-bis-(4,6-dimethylpyrimidine-2-thiolato)managanese(II) have been determined by X-ray diffraction. In the manganese complex the metal has a distorted octahedral trans-MnS2N4 geometry with one nitrogen atom of each pyrimidine ligand uncoordinated.
