Zusammenfassung:The asymmetric unit of the title compound {systematic name: 4‐(6‐fluoro‐1,2‐benzisoxazol‐3‐yl)‐1‐hydr­oxy‐1‐[2‐(2‐methyl‐4‐oxo‐3,4,6,7,8,9‐hexa­hydro‐2H‐pyrido[1,2‐a]pyrimidin‐3‐yl)­eth­yl]piperidine}, C23H27FN4O2, contains two independent risperidone mol­ecules. The piperidine and the tetra­hydro­pyridine rings adopt chair and sofa conformations, respectively.
