Abstract:
The complex Cu 2 (O 2 CCH=CHCH 3 ) 4 (DMF) 2 was synthesized from Cu(OH) 2 , trans-2-butenoic acid, and dimethylformamide. An X-ray structure determination showed that the complex has the familiar Cu 2 (O 2 CR) 4 L 2 dimer structure. trans-2-Butenoate groups in molecules related by a center of symmetry have a short contact between the α-carbon atoms (3.611 Å), suggesting a study of the solid-state reactivity of this complex. Irradiation of the complex ( 60 Co X-rays, 219 kGy), did not produce any detectable product. Magnetic susceptibility measurements in the range between 2 and 350 K in a powder sample, and EPR measurements in powder and single-crystal samples were performed. The data show the dimeric magnetic structure of the compound, with an antiferromagnetic exchange coupling J/k(B) = -220 K and a fine structure coupling D/h = -10.04 GHz within the excited spin triplet. Hyperfine structure with the two Cu nuclei is clearly observed. These results are discussed in terms of the structure. (C) 2000 Elsevier Science B.V.
