A series of [Mn 6 O 2 ( R 1 OH) 4 (sao) 6 ( R 2 COO) 2 ] complexes with terminal functional groups ( 1 : R 1 = CH 3 , R 2 = HO‐C 6 H 4 , 2 : R 1 = C 2 H 5 , R 2 = H 2 N‐C 6 H 4 , 3 : R 1 = CH 3 , R 2 = Cl‐C 6 H 4 , 4 : R 1 = CH 3 , R 2 = CH 3 S‐C 6 H 4 , 5 : R 1 = CH 3 , R 2 = I‐C 6 H 4 , 6 : R 1 = CH 3 , R 2 = pymSCH 2 , 7 : R 1 = CH 3 , R 2 = ortho ‐pyr‐SCH 3 , 8 : R 1 = C 2 H 5 , R 2 = (CH 3 ) 3 OOCNHCH 2 C 6 H 4 ; sao = doubly deprotonated salicylaldoxime ligand, pym = pyrimidyl, pyr = pyridyl) have been obtained in a reaction of a ligand R 2 C 6 H 4 COOH, salicylaldoxime, manganese(II) perchlorate and [NEt 4 ](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 Mn 2+ ions, whereas 4 and 7 show ferromagnetic interactions. The title compounds may act as starting materials for further derivatization addressing the functional groups.
