μ-[1,1'-(1,2-Ethanediyl)bis(1H-1,2,4-triazole)]-N4 :N4'-bis{bis[1,1,1-trifluoro-3-(2-thenoyl)acetonato-O, O']copper(II)}

The crystal structure determination of the title complex, [Cu 2 (C 8 H 4 F 3 O 2 S) 4 (C 6 H 8 N 6 )] or [Cu(TTA) 2 ] 2 btrz, where TTA is 1,1,1-trifluoro-3-(2-thenoyl)acetone and btrz is μ-[1,1'-(1,2-ethanediyl)bis( 1H-1,2,4-triazole)], shows that the btrz ligand links two Cu II ions, forming a binuclear complex. Each Cu atom is in a distorted square-pyramidal coordination environment.
