Abstract
The hydrothermal synthesis and single crystal XRD characterization have been performed for two manganese phosphonocarboxylates, Mn3(O3PCH2COO)21 and Mn3(O3PCH2CH2COO)22. Compound 2 forms a pillared structure related to that of the analogous zinc compound and 1 exhibits a three-dimensional network; MnO5 and MnO6 polyhedra are observed and all oxygens take part in coordination of the Mn2+ ions. Magnetization measurements of 1 and 2 indicate weak ferromagnetic and antiferromagnetic ordering, respectively, at low temperatures. Thermogravimetric analyses show the structure to be stable up to 430 and 400 °C for 1 and 2, respectively.Keywords
