Cu(II) complexes of the tridentate thiosemicarbazone ligands diacetyl monooxime thiosemicarbazone (dmoTSCH(2)) and diacetyl monooxime (4-phenyl)thiosemicarbazone (dmoPhTSCH(2)) have been synthesized. X-ray crystal structures of dmoPhTSCH(2) and [Cu(dmoTSCH)Cl](2)center dot H2O (1 center dot H2O) are also reported. The Cu(II) compound 1 center dot H2O is a dinuclear complex, where the Cu(II) centers have a square pyramidal geometry and are bridged by two thiolato ligands. A C-2 axis passes through the middle of Cu2S2 rectangle. Variable temperature susceptibility measurement for 1 center dot H2O shows that this compound exhibits a very weak antiferromagnetic behavior (in the solid state) with J(1) = -2.97 cm(-1), using the Heisenberg isotropic spin Hamiltonian (H = -J(1)S(1)center dot S-2). DFT calculations show that the intramolecular magnetic interaction should be ferromagnetic, and the net antiferromagnetic behavior is due to competition with antiferromagnetic intermolecular interactions through hydrogen bonds.
