Crystal structure of 7′-(4-chloroohenyl)-2"-(4-methoxyphenyl)-7′,7a′,7",8"-tetranydro-1′H,3′H,5"H-disoiro[indoline-3,5′-pyrrolo[1,2-c]-thiazole-6′,6"-quinoline]-2,5"-dione and an unknown solvent

The asymmetric unit of the title compound, C34H28ClN3O3S, contains two independent molecules (A and B). They differ essentially in the orientation of the 4-methoxyphenyl ring with respect to the pyridine ring of the quinoline moiety; this dihedral angle is 37.01 (18)degrees in molecule A but only 7.06 (17)degrees in molecule B. In both molecules, the cyclohexanone ring of the isoquinoline unit has a half-chair conformation. In the pyrrolothiazole ring system, the pyrrolo ring in molecule A has a twisted conformation on the N-C fused bond and an envelope conformation in molecule B with the N atom as the flap. The thiazole rings of both molecules have twisted conformations on the N-C fused bond. In the crystal, the A molecules are linked by pairs of N-H center dot center dot center dot O hydrogen bonds, forming inversion dimers with an R-2(2)(8) ring motif. These dimers are linked to the B molecules by an N-H center dot center dot center dot N hydrogen bond and a series of C-H center dot center dot center dot O hydrogen bonds, forming layers lying parallel to the (101) plane. The layers are linked by C-H center dot center dot center dot pi interactions and offset pi-pi interactions [intercentroid distance = 3.427 (1) angstrom], forming a supramolecular framework. The contribution to the scattering from a region of highly disordered solvent molecules was removed with the SQUEEZE routine in PLATON [Spek (2015). Acta Cryst. C71, 9-18]. The solvent formula mass and unit-cell characteristics were not taken into account during refinement.
