ABSTRACT

A new heterometallic lanthanide-titanium-organic compound: [Eu2Ti2(dip)6(dig)2(H3O)2]·solvent (1, dip = diphenylglycolic acid, dig = diglycolic acid) has been synthesized under solvothermal conditions. Compound 1 contains a tetra-nuclear {Eu2Ti2} unit with the mixed ligands of dip and dig. Compound 1 displays intense red luminescence. Furthermore, the IR, PXRD, UV-vis and TGA spectra were also studied.
