Spin Frustrated Double Chain {[Fe(PZDA)H2O)2].2H2O}n (H2PZDA=2,3-Pyrazinedicarboxylic Acid)

A novel compound {[Fe(PZDA)(H2O)2].2H2O}n has been synthesized and its structure determined by X-ray diffraction analysis, which consists of a quasi-ladder-like double chain running along a axis where Fe(II) ions are linked through the carboxylic groups acting as the edges of the ladder and pyrazine rings functioning as the rungs. Variable-temperature magnetic susceptibility study indicates the presence of spin frustration in the double chain compound.
