A sandwich-type europium-substituted germanomolybdate, H(H(2)en)(5)[Cu(en)(2)] [Eu(GeMo11O39)(2)]center dot 11H(2)O (1) (en = ethylenediamine) has been synthesized and structurally characterized by elemental analysis, IR spectroscopy, UV electronic spectroscopy, thermogravimetric analysis and single crystal X-ray diffraction. Complex 1 displays a one-dimensional zigzag chain framework built up from the [Eu(GeMo11O39)(2)](13-) polyanions alternatively linked by [Cu(en)(2)](2+) cations. The photoluminescence property of solid samples for compound 1 has been investigated, and the spectrum exhibits obvious red fluorescence. The magnetic investigation on complex 1 indicates that the magnetic behavior attributes to a combined effect of depopulation and intermolecular antiferromagnetic interactions.
