Abstract
The crystal structure of paliperidone palmitate has been solved and refined using synchrotron X-ray powder diffraction data, and optimized using density functional techniques. Paliperidone palmitate crystallizes in space group P21/c (#14) with a = 34.415 40(35), b = 10.093 49(7), c = 10.904 92(9) Å, β = 94.3917(9)°, V = 3776.94(6) Å3, and Z = 4. The conformation of the paliperidone fragment differs from that of the parent compound. The palmitate chain exhibits a slight twist close to the ester group. Several C–H⋅⋅⋅O hydrogen bonds contribute to the crystal packing, which is dominated by van der Waals interactions. The powder pattern is included in the Powder Diffraction File™ as entry 00-066-1614.
