4-[(3-Benzamidomethyl-6-phenyl-6,7-dihydro-5H-1,2,4-triazolo[3,4-b][1,3,4] -thiadiazin-7-yl)carbonyl]-3-phenyl-1,2,3-oxadiazol-3-ium-5-olate 0.06-hydrate

Abstract

The asymmetric unit of the title compound, C27H 21N7O4S·-0.06H2O, contains four syndone molecules and a water molecule with a site occupancy of 0.25. In two of the syndone molecules, three atoms in a terminal phenyl ring are disordered over two sets of sites, with occupancy ratios of 0.500 (18):0.500 (18) and 0.512 (17):0.488 (17). The dihedral angles between terminal phenyl rings for the syndone molecules are 23.3 (4), 45.57 (16), 68.46 (16) and 56.5 (3)°. In the crystal, molecules are connected via N - H⋯N, N - H⋯O, O - H⋯O, O - H⋯N and C - H⋯O hydrogen bonds, forming a three-dimensional network.
