Bis(isoquinolin-2-ium) tetra-chlorido-zincate dihydrate.

In the title compound, (C9H8N)2[ZnCl4]·2H2O, the tetra-chlorido-zincate ion is located on a twofold rotation axis with the Zn atom on a special position. The crystal packing is stabilized by N-H⋯O and O-H⋯Cl inter-actions.

6'-(1,3-Diphenyl-1H-pyrazol-4-yl)-7'-(1H-indol-3-ylcarbon-yl)-2-oxo-1-(prop-2-en-1-yl)-5',6',7',7a'-tetra-hydro-1'H-spiro-[indoline-3,5'-pyrrolo-[1,2-c][1,3]thia-zole]-7'-carbo-nitrile.

In the title compound, C41H32N6O2S, the pyrrolo-thia-zole ring system is folded about the bridging N-C bond. The thia-zolidine and pyrrolidine rings adopt envelope (with the fused C atom as the flap) and twisted conformations, respectively. The two phenyl rings attached to the pyrazole ring are twisted from the plane of the latter by 6.

Ethyl 1''-benzyl-1'-methyl-2''-oxodi-spiro-[indeno-[1,2-b]quinoxaline-11,3'-pyrrolidine-2',3''-indoline]-4'-carboxyl-ate.

In the title compound, C36H30N4O3, the quinoxaline-indene system is roughly planar, with a maximum deviation from the mean plane of 0.218 Å for the C atom shared with the central pyrrolidine ring. This latter ring forms dihedral angles of 84.
