The structure of tetraethylammonium trichlorooxo (1,1,1-trifluoro-4-thenoyl-2,4-butanedionato)niobate(V) has been determined by single crystal X-ray analysis. Crystals are monoclinic: a = 12.495(2) Å; b = 11.392(2) Å; c = 16.940(3) Å; β = 101.0(1)°; V = 2334 Å3; space group P21/c, Z = 4. The structure was solved from Patterson and electron density maps and refined be least-square methods to a conventional R value of 0.04 for 2409 independent non zero reflexions. The structure determination shows that the thenoyl group is 'trans' with respect to the NbO bond.
