Hirshfeld surface analysis of two bendroflumethia­zide solvates

Bendroflumethiazide, or 3-benzyl-6-(trifluoro­meth­yl)-3,4-dihydro-2H-1,2,4-benzothia­diazine-7-sulfonamide 1,1-dioxide, is reported to crystallize as 1:1 solvates with acetone, C₁₅H₁₄F₃N₃O₄S₂·C₃H₆O, and N,N-dimethyl­formamide, C₁₅H₁₄F₃N₃O₄S₂·C₃H₇NO. A detailed investigation of the crystal packing and inter­molecular inter­actions is presented by means of Hirshfeld surface analysis. This analysis confirms the atomic positions of methyl H atoms of the solvent mol­ecules that were inferred from the X-ray data and provides a useful tool for structure validation.
