The crystal structure of 2-thoiphenecarboxamide is described. The compound crystallizes in the orthorhombic Pna21 space group with unit cell parameters a = 10.044 (3) Å, b = 14.203 (4) Å and c = 15.941 (3) Å; V = 2,274.1 (10) Å3. The asymmetric unit contains four independent molecules which are linked by N–H···O hydrogen bonds. The asymmetric unit at (x, y, z) is connected with another one, produced by the a-glide plane at 0.75 along the b-axis, that lies at (x + 0.5, −y + 1.5, z) by two N–H···O hydrogen bonds and by a C–H···O weak hydrogen bond to form a one-dimensional tube. Adjacent tubes are linked by C–H···pi interactions to form a three-dimensional framework.
