| Popis: | 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). |
