摘要：
A new complex, [Cu-2(sulfameter)(4)](3) center dot 2.5H(2)O (sulfameter = 4-amino-N-(5-methoxy-2-pyrimidinyl)benzenesulfonamide), has been synthesized. Its structure has been determined by single-crystal X-ray diffraction and its spectroscopic properties (EPR, IR, Raman, UV-Vis) have been analyzed. The structure presented three different dimeric units in the unit cell and the EPR spectra, characteristic of antiferromaanetically coupled dimers, revealed two magnetically different dimeric environments.
