摘要

A series of [Mn6O2(R1OH)4(sao)6(R2COO)2] complexes with terminal functional groups (1: R1 = CH3, R2 = HO-C6H4, 2: R1 = C2H5, R2 = H2N-C6H4, 3: R1 = CH3, R2 = Cl-C6H4, 4: R1 = CH3, R2 = CH3S-C6H4, 5: R1 = CH3, R2 = I-C6H4, 6: R1 = CH3, R2 = pymSCH2, 7: R1 = CH3, R2 = ortho-pyr-SCH3, 8: R1 = C2H5, R2 = (CH3)3OOCNHCH2C6H4; sao = doubly deprotonated salicylaldoxime ligand, pym = pyrimidyl, pyr = pyridyl) have been obtained in a reaction of a ligand R2C6H4COOH, salicylaldoxime, manganese(II) perchlorate and [NEt4](OH) in methanol or a 1:1 mixture of ethanol and dichloromethane. In this report, structural aspects as well as preliminary studies of magnetic and thermal properties are presented. Compounds 1, 3, 6, 8 exhibit an antiferromagnetic coupling of the Mn2+ ions, whereas 4 and 7 show ferromagnetic interactions. The title compounds may act as starting materials for further derivatization addressing the functional groups.
