Synthesis and characterisation of transition metal containing polycarboxylates

Macromolecule metal composites are promising candidates for materials with special magnetic, optical and electrical properties. The synthesis and characterisation of copper(II) and nickel(II) complexes of poly-(exo,exo-7-oxabicyclo[2.2.1]hept-5-en-2,3-carboxylic acid) are presented. Infrared spectroscopy and x-ray diffractometry gave information about the structural properties. The compounds showed weak antiferromagnetic interactions, but no phase transitions in the temperature range 4.2–200 K.
