The thermolysis and reactions of the polymeric high spin MnII and FeII complexes [Mn(μ-OOCBut)2(HOEt)] n (1) and [Fe(μ-OOCBut)2]n (3) with pivalic acid and o-phenylenediamines 1,2-(NH2)2C 6H2R2 (R = H or Me) were studied. The synthesis of compound 1 performed with a deficiency of pivalate anions affords the antiferromagnetic chloropivalate polymer { (MeCN)(HOOCBut)(H 2O)Mn5Cl(OH)(OOCBut)8?MeCN} n. The reaction of 1 with an excess of pivalic acid produces the antiferromagnetic polymer [Mn4(OOCBut) 8(HOOCBut)2]n. The analogous reaction of pivalic acid with polymer 3 gives the mononuclear complex Fe(η 1-OOCBut)2(η1-HOOCBu t)4 containing the high spin iron(II) atom as the major product. Study of the reactions of 3 with a deficiency (1: 1) of diamines demonstrated that the polymer {[(η2- (NH2)2C6H4)2Fe(μ- OOCBut)2][Fe2(μ-OOCBut) 4] ? ? 2MeCN}n is generated as the major product in the former case, whereas the mononuclear complexes Fe(η1- OOCBut)2[η1-(NH2) 2C6H4]4 and Fe(η1- OOCBut)2[η2-(NH2) 2C6H2Me2][η1-(NH 2)2C6H2Me2]2 are predominantly obtained in the latter case.
