| Abstract: | The interaction of [K2FeIII 4(O)2(OOCCMe3)10(HOOCCMe3)2(H2O)2]n with 2-pyridinecarboxaldehyde results in a mixed-valence complex FeIIFeIII 3(μ3-O)2(μ2-OOCCMe3)7L2··2.5MeCN·3H2O (L = 2-NC5H4COOH0.75K0.25). The structure of the complex was established by X-ray analysis. The magnetic properties of the complex were studied. Dedicated to Academician A. L. Buchachenko on the occasion of his 70th birthday. Published in Russian in Izvestiya Akademii Nauk. Seriya Khimicheskaya, No. 9, pp. 2145–2148, September, 2005. |
