Abstract :
Reactions of [Cu2(O2CMe)4(H2O)2] or Cu(O2CPh)2 · 2H2O with 2 or 1, respectively, molar equivalents of di-2-pyridyl ketone oxime, (py)2CNOH, in MeCN-based solvent mixtures yield complexes image (1, R = Me; 2, R = Ph). Crystal structures of these compounds show similar triangles of CuII ions, centered by a triply bridging hydroxo ligand and with three edge-bridging oximate groups from the three 2.1110 (py)2CNO− ions. Preliminary variable-temperature magnetic susceptibility studies and EPR data at 4.2 K for 1 reveal an antiferromagnetically-coupled system showing antisymmetric exchange.
