Abstract
A new bis(oxalato)chromium(III) salt of formula (C5H6ClN2)[Cr(C2O4)(2)(H2O)(2)]center dot 2H(2)O has been synthesized and characterized by single crystal X-ray diffraction. Its structure reveals a three-dimensional supramolecular network formed by hydrogen bonding and pi-pi stacking interactions. Thermal analysis showed that the compound is stable up to 134 degrees C and magnetic susceptibility measurements revealed the occurrence of weak antiferromagnetic interactions between the chromium centers (T<14K), in agreement with the crystal structure.
