Résumé

The reactions of (2-propanol)yttrium triiodide, Y(iPrOH)4I3, with stoichiometric amounts of water in the presence of di-, tri-, and tetraglyme yield a facile synthetic route to hydroxo-bridged, centrosymmetric dimeric yttrium complexes. These ionic derivatives, [Y2L2(-OH)2(H2O)x(ROH)y]I4 [1: L = triglyme, x = 2, y = 2, R = iPr; 2: L = tetraglyme, x = 2, y = 0; 3·2EtOH: L = diglyme, x = 2, y = 4, R = Et; 4·2EtOH: L = triglyme, x = 4, y = 0; 5: L = tetraglyme, x = 2, y = 2, R = Et] have been characterized by elemental analysis, IR and 1H NMR spectroscopy, as well as by single-crystal X-ray diffraction for 3, 4, and 5. Preliminary results on the utility of these ionic derivatives as potential sources of yttrium oxide in high Tc superconductors are also presented.
