TL;DR: In this paper, a series of 4-arylidene and 2-methyloxazol-5-ones were condensed with thiosemi-carbazide to yield 6-arylmethylmethyl-3-mercapto•1,2,4-triazin•5−ones, and the resulting triazinones were tested for their antibacterial activity against Gram (+)ve and Gram (−)ve bacteria.

TL;DR: The racemic title compound, C15H12Br2O, crystallizes in a non-centrosymmetric structure and displays a significant non-linear optical response to red light.
Abstract: The racemic title compound, C15H12Br2O, crystallizes in a non-centrosymmetric structure and displays a significant non-linear optical response to red light. The crystal packing is influenced by C—H⋯O and C—H⋯π inter­actions. One of the former bonds has a short H⋯O separation of 2.27 A.

TL;DR: The title compound, C23H15BrClFN4O, is an analogue of sedatives such as midazolam and alprazolam, and its geometrical parameters are normal and comparable with those of related compounds as discussed by the authors.
Abstract: The title compound, C23H15BrClFN4O, is an analogue of sedatives such as midazolam and alprazolam. Its geometrical parameters are normal and comparable with those of related compounds. The only possible significant inter­molecular inter­action is a C—H⋯O bond.
