Abstract

A new discrete hexanuclear, mixed-valence Mn oxide cluster, [Mn6O2(O2CEt)10(H2O)4] (1), has been prepared and used as the building unit for the self-assembly of a rare propionato-bridged zigzag-like chain polymer, [Mn6O2(O2CEt)10(H2O)4]n (2), with the retention of the Mn6 core of 1. Both complexes are characterized by single-crystal X-ray structure determinations and magnetic measurements. The discrete complex 1·3H2O crystallizes in orthorhombic space group Pnna with a = 14.2089(6), b = 21.4910(11), and c = 16.4247(6) Å, whereas the polymeric complex 2·2nEtCO2H crystallizes in orthorhombic space group Pbca with a = 13.651(4), b = 25.827(8), and c = 30.312(10) Å. Variable-temperature magnetic susceptibility analyses show the presence of moderately strong antiferromagnetic interactions within the Mn6 cluster unit in both complexes.(© Wiley-VCH Verlag GmbH & Co.
