ABSTRACT

Reaction of Ba(NO₃)₂ with Fe(NO₃)_3·9H₂O and H₂C₂O_4·2H₂O in aqueous medium readily affords, in high yield, the bimetallic complex polymer of chemical composition {Ba₆(H₂O)₁₇[Fe(C₂O₄)₃]₄}·7H₂O (1), consistent with the expected ratio of 3Ba^II vs. 2Fe^III. Compound 1 was fully characterized by elemental and thermal analyses, vibrational FTIR spectroscopy, and by single crystal X-ray structure determination. The bulk structure of 1 is a 3-D metal-organic framework held together by intermetallic linkages across oxalate and aqua oxygen bridgings. Thermal analyses of 1 show significant weight losses corresponding to water molecules (lattice and coordinated), followed by the decomposition of the network.
