| Summary: | A new polymorph of <i>N</i>-(1,3-thiazol-2-yl)benzamide crystallises in the monoclinic space group <i>Pc</i> with four crystallographically independent molecules (Z′ = 4) in the asymmetric unit. Where the previously reported polymorphs exhibit two distinct hydrogen-bonded dimer geometries exclusively, the asymmetric unit of the new polymorph comprises both. Approximate symmetry was observed to relate the molecules of these dimers. These approximate symmetry elements combine to form a structure with distorted <i>P</i>2<sub>1</sub>/<i>c</i> space group symmetry, rationalising the unexpectedly high number of crystallographically independent molecules. |
