Abstract

The dinuclear copper(II) complex [Cu(tda)(phen)]2 · H2tda (tda=thiodiacetate; phen=1,10-phenanthroline) has been prepared and characterized by single crystal X-ray diffraction. The dimer shows a strictly planar CuO2Cu ring involving monoatomic O-carboxylates in the bridging mode with each copper weakly bonded to a thioether in a distorted octahedral N2O3S environment. Variable temperature susceptibility measurements reveal the existence of weak ferromagnetic interactions within the dimer, mediated by the oxygen atoms of the bridge. © 1999 Elsevier Science S.A.
