Аннотация
Olanzapinium benzoate, 1-methyl-4-(2-methyl-10H-thieno[2,3-b][1,5]benzodiazepin-4-yl)-piperazin-1-ium benzoate, (C17H21N4S)+(C7H5O2)– (I), crystallizes in triclinic space group P-1 with unit cell dimensions a = 9.2957(6), b = 11.2416(7), c = 12.0003(8) Å ; a = 64.585(1), b = 87.568(1), g = 83.248(1)° ; V = 1124.8(1) Å 3. The asymmetric part of the structure comprises a singly charged olanzapinium cation and a singly charged benzoate anion. The central 1,5-diazepine ring adopts the expected boat conformation, while the piperazine ring favors the chair conformation. The olanzapinium and benzoate ions are linked by intermolecular N—H…O hydrogen bonds forming infinite chains running along the c-axis of the crystal.
