Abstract

Crystal structures are reported for three amides containingN-benzo[d]thiazolesubstituents. InN-(benzo[d]thiazol-6-yl)-3-bromobenzamide, C14H9BrN2OS,where the two ring systems are nearly parallel to one another [dihedral angle= 5.8 (2)�], the molecules are linked by N—H���O and C—H���N hydrogenbonds to form ribbons ofR33(19) rings, which are linked into sheets by shortBr���Br interactions [3.5812 (6) A ̊].N-(6-Methoxybenzo[d]thiazol-2-yl)-2-nitro-benzamide, C15H11N3O4S, crystallizes withZ0= 2 in space groupPna21:thedihedral angles between the ring systems [46.43 (15) and 66.35 (13)�] aresignificantly different in the independent molecules and a combination of twoN—H���N and five C—H���O hydrogen bonds links the molecules into a three-dimensional network. The molecules of 5-cyclopropyl-N-(6-methoxyben-zo[d]thiazol-2-yl)isoxazole-3-carboxamide, C15H13N3O3S, exhibit two forms ofdisorder, in the methoxy group and in the cyclopropylisoxazole unit; symmetry-related pairs of molecules are linked into dimers by pairwise N—H���Nhydrogen bonds. Comparisons are made with the structures of some relatedcompounds
