Crystal Structure of Flecainide Acetate

Abstract

Flecainide is antiarrhythmic drug. The structure of flecainide acetate, N-(2-piperidylmethyl)-2,5-bis-(2,2,2-trifluoroethoxy)benzamide acetate (C17H19F6N2O3) (C2H4O2), was determined by X-ray crystallography. The compound crystallizes in a monoclinic system, space group P21/n and cell parameters: a = 5.3304 (5) Å, b = 14.2568 (6) Å, c = 28.530 (1) Å, β = 93.08(4) ˚, Z = 4, V = 2420.0 (3) Å3
