摘要：
Several reaction schemes involving di-2-pyridyl ketone oxime, (py)(2)CNOH, Mn sources, RCO2- ligands and X- in MeCN or MeCN/EtOH lead to the new family of mixed-valence complexes [(Mn2Mn2III)-Mn-II(O2CR)(2)X-2{(py)(2)CNO}(2){(py)(2)CO2}(2)] (R = Me, Ph; X = Cl, Br; (py)(2)CO22- = the gem-diolate(-2) form of di-2-pyridyl ketone). The products have been characterized by single crystal X-ray crystallography and exhibit the same structural motif Magnetic studies indicate weak antiferromagnetic exchange interactions in the complexes.
