An amide cyclo­phane

The title compound, 8,18-dithia-2,6-diaza-13(1,4)-piperidina-1(1,2),4(1,3),7(1,2)-tribenzenaoctadecaphane-10,15-diyne-3,6-dione, C₃₂H₃₀N₄O₂S₂, is composed of a relatively planar bis­(2-mercaptophen­yl)isophthalamide unit linked to a bridging 1,4-di(but-2-yn-1-yl)piperazine unit, forming a macrocycle. The isophthalamide ring is inclined to the outer mercaptophenyl rings by 8.18 (11) and 5.59 (10)°, while these two rings are inclined to one another by 9.10 (12)°. The piperazine ring adopts a chair conformation. There are two intra­molecular N—H...S hydrogen bonds generating S(5) ring motifs. In the crystal, mol­ecules are linked via C—H...S and C—H...O hydrogen bonds, forming slabs lying parallel to (001). An O atom in the isophthalamide group is disordered over two positions with an occupancy ratio of 0.41 (6):0.59 (6).

Crystal structure of 4-acetyl­phenyl 3-methyl­benzoate

The planes of the aromatic rings of the title compound, C₁₆H₁₄O₃, make a dihedral angle of 82.52 (8)°. The acetyl group and the phenyl ring make a dihedral angle of 1.65 (1)°. In the crystal, the molecules are linked by C—H...O interactions, generating C(7) chains along the a-axis direction.

Crystal structure of 6-(4-chloro­phen­yl)-6a-nitro-6,6a,6b,7,9,11a-hexa­hydro­spiro[chromeno[3′,4′:3,4]pyrrolo­[1,2-c]thia­zole-11,11′-indeno­[1,2-b]quinoxaline] chloro­form monosolvate

In the title compound, C₃₃H₂₃ClN₄O₃S·CHCl₃, the thia­zole ring adopts an envelope conformation with the N atom as the flap, and the pyrrolidine ring adopts a half-chair conformation. The thia­zole ring mean plane makes a dihedral angle of 59.31 (1)° with the pyrrolidine ring mean plane, 71.67 (1)° with the chromene ring and 82.59 (1)° with the chloro­benzene ring. An intra­molecular C—H...N hydrogen bond occurs. In the crystal, a second C—H...N hydrogen bond links the main and solvent mol­ecules. The solvent chloroform molecule is disordered about two positions with an occupancy ratio of 0.508 (14):0.492 (14).
