Abstract

The crystal structure of daclatasvir dihydrochloride Form N-2 (Daklinza®) has been refined using synchrotron X-ray powder diffraction data and optimized using density functional theory techniques. Daclatasvir dihydrochloride, Form N-2, crystallizes in space group P1 (#1) with a = 7.54808 (15), b = 9.5566 (5), c = 16.2641 (11) Å, α = 74.0642 (24), β = 84.0026 (13), γ = 70.6322 (5)°, V = 1064.150(11) Å3, and Z = 1. The hydrogen bonds were identified and quantified. Strong N–H⋯Cl hydrogen bonds link the cations and anions in chains along the a-axis. The powder pattern has been submitted to ICDD® for inclusion in the Powder Diffraction File™ (PDF®).
