Crystal structure of N,N '-Ethylenebis(1,1,1-Trifluoro-4-iminopentan-2-one)

Abstract

The crystal structure of N,N'-ethylenebis(1,1,1-trifluoro-4-iminopentan-2-one) (tfaen) was determined: C₁₂H₁₄F₆N₂O₂, M 342.04, monoclinic, space group P2₁/n, a 6.939(2), b 20.529(5), c 10.662(2) Å, V 1507.84 ų β 96.87(2)º, p(calc.) 1.506 g cm^-3 (Z = 4), F(000)680, µ(Cu Kα) 13.15 cm^-1. The structure was solved by direct methods and refined to a final R value of 0.073 for 1198 unique reflections. Discrete molecules in the crystal are characterized by a conjugated enamino ketone structure with intramolecular hydrogen bridges.
