Abstract :
An antiferromagnetic pivalate polymer complex [Mn(OOCCMe3)2(EtOH)]n (1) has been prepared by the reaction between MnCl2 · 4H2O and KOOCCMe3 in EtOH. The reaction of 1 with 2,6-diaminopyridine (L) in MeCN resulted in an antiferromagnetic binuclear L2Mn2(μ-OOCCMe3)4 (2) complex solvated with the four acetonitrile molecules. The oxidation of 1 was shown to give rise to a hexanuclear pivalate cluster Mn6(μ4-O)2(μ-OOCCMe3)10(HOOCCMe3)(HOEt)3 (3). Both the X-ray and the thermographic studies revealed low temperature phase transitions for 1 and 2.
