Abstract
Tetrabutylammonium 4-(2-bromothiophene-5-sulfanilamide)-benzoate crystallizes in C2/C lattice with a = 18.3389(17), b = 16.540(16), c = 15.8280(15) Å, β = 116.959(2), V = 4279.5(7) Å3, Z = 4, and R = 0.0560. In the structure a very short centrosymmetric hydrogen bond and C=O···Br halogen bond interactions, together with N–H···O and C–H···O hydrogen bonds give a three-dimensional network.Graphical AbstractA extremely short O–H···O hydrogen bond is observed between the two neighboring 4-(2-bromothiophene-5-sulfanilamide)-benzoates. The H atom is fixed at the crystallographic inversion center and bridges the two benzoates to form an anion dimer. Halogen bonds also aid in forming the interest structure in crystal.
