The title compound [Cu6(HL)6] (HL＝N-ethoxycarbonyl-N'-(4-fluorophenyl)-thiourea) was synthesized from L and Cu(NO3)2•3H2O in ethanol, and characterized by elemental analysis, IR, 1H NMR, thermogravimetry and differential thermal analysis with its crystal structure determined by X-ray single crystal diffraction. The crystal of compound belongs to triclinic system with space group and parameters: a＝1.2508(11) nm, b＝1.3011(11) nm, c＝1.4686(12) nm, α＝102.401(14)°, β＝97.859(2)°, γ＝114.700(13)°, V＝2.051(3) nm3, Z＝1, Dc＝1.687 Mg/m3. The title compund is a cage shaped metal cluster consisting of six copper(II) and six thiourea ligands.
