A new trinuclear copper complex based on germanomolybdate, {[Cu(phen)](3)(mu(2)-Cl)(4)}(2)[GeMo12O40] (1) (phen =1,10-phenanthroline). has been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectroscopy, TG analysis, X-ray powder diffraction (XRPD) and single-crystal X-ray diffraction. Single crystal X-ray analysis reveals that the structural unit of 1 consists of two coordination cations {[Cu(Phen)](3)(mu(2)-Cl)(4)}(2+) (1a) and a saturated Keggin-type germanomolybdate polyoxoanion [GeMo12O40](4-) In 1, the most intriguing feature is that each trinuclear copper cation {[Cu(phen)](3)(mu(2)-Cl)(4)}(2+) is constructed from three [Cu(phen)](2+) cations bridged by four mu(2)-Cl atoms. Magnetic measurements indicate 1 shows the ferromagnetic exchange interactions within Cu-II centers.
