Popis: | A new chloro-oxo-alkoxide, Sr2Er2OCl(OPr i )7(HOPr i )4 has been prepared by reacting 4ErCl3 with 5Sr dissolved in toluene:HOPr i . The structure, determined by single-crystal X-ray techniques, is built from two polymer strands, each formed by repeating two molecular Sr2Er2O(OPr i )7(HOPr i )4 complexes, inter-tied by a chloro atom. The four independent, but very similar complexes contain two Er and two Sr ions, all binding to a central oxo ion. The great similarity of the FT-IR and UV-vis-NIR spectra of the solid and the hexane/toluene/2-propanol solutions shows that the molecular complexes have similar complex structures in the solid state and in solution. |
