Possible cobalt-cobalt bridging by a hemiacetal in the dinuclear cobalt complex bearing the ligand bis(3-(2-Pyridylmethyleneamino)phenyl) sulfone
A dinuclear cobalt complex bearing the ligand bis(3-(2-pyridylmethyleneamino)phenyl) sulfone (BPMAPS) was prepared. It is proposed that the structure of this is [Co2(BPMAPS)(m-OAcM)2(hemi-Et)]PF6 wherein the cobalt centers are bridged by two carboxylato groups in m-fashion and a hemiacetal with an ethoxy group (hemi-Et). This proposal is based on the similarity of the FT-IR, UV-Vis, and FAB-MS results with the crystallographically characterized dinuclear manganese complex [Mn2(BPMAPS)(m-OAc)2(hemi-Me)]PF6, and elemental analysis results.
