Abstract

Bis[2-(benzylamido)pyridine]trichloroniobium(V) (1) and bis[2-(benzylamido)pyridine]trichlorotantalum(V) (2) have been synthesised in a melt reaction of 2-(benzylamino)pyridine and corresponding metal(V) halide. Both complexes were crystallised from toluene which was used for extraction. Solvate molecules are also found in the solid-state structures; the Nb compound crystallises with two complex molecules and two solvate molecules in the asymmetric unit, whereas in 2 the number of metal complexes and toluene molecules in the asymmetric unit is one. Compound 1 crystallises in monoclinic space group P2(1)/c with unit-cell parameters of a = 18.292(8) Angstrom, b = 19.904(15) Angstrom, c = 17.646(10) Angstrom and beta = 109.47(4). Compound 2 crystallises in P2(1)/n with unit-cell parameters a = 9.227(8) Angstrom, b = 20.005(7) Angstrom, c = 16.804(6) Angstrom and beta = 100.08(5) Angstrom. The coordination spheres around the transition metals are pseudo-pentagonal bipyramids.
