Synthesis, structure and magnetic properties of a quasi-two-dimensional compound [Cu(C 5 H 4 NCOO) 2 ] · 2H 2 O

A new compound [Cu(C 5 H 4 NCOO) 2 ] · 2H 2 O has been prepared. Its structure consists of a chain built from [Cu(C 5 H 4 NCOO) 2 ] units, bridged through weak interactions between the copper(II) atoms and the O atoms of the carboxylate groups of a adjacent [Cu(C 5 H 4 NCOO) 2 ] units. I.r. spectra, thermal analysis and elemental analysis have been recorded for the complex. Room temperature X-band e.s.r. spectra of powered samples and variable-temperature magnetic susceptibility studies indicate that the compound exhibits a weak ferromagnetic interaction through Cu—O—C—O—Cu pathways.
