Crystal structure and Hirshfeld surface analysis of 1-methyl-4-(2-methyl-10H-benzo[b]thieno[2,3-e][1,4]diazepin-4-yl)piperazin-1-ium 2,5-di­hy­droxy­benzoate propan-2-ol monosolvate

The asymmetric unit of the title salt, C17H21N4S+·C7H5O4−·C3H7OH, consists of an olanzapinium cation, an independent 2,5-di­hydroxy­benzoate anion and a solvent isopropyl alcohol mol­ecule. The central seven-membered heterocycle is in a boat conformation, while the piperazine ring displays a distorted chair conformation. The dihedral angle between the benzene and thiene rings flanking the diazepine ring is 52.58 (19)°. In the crystal, the anions and cations are connected by N—H⋯O and O—H⋯O hydrogen bonds, forming a three-dimensional network.
