1-(4-Bromo-phen-yl)-3-butano-ylthio-urea
Abstract:
In the title compound, C(11)H(13)BrN(2)OS, there are two independent mol-ecules (A and B) in the asymmetric unit. The dihedral angle between the mean planes of the benzene ring and the carbamothioyl group is 63.66 (mol-ecule A) and 80.3 (0)° (mol-ecule B). The butanamide group in mol-ecule A is disordered [0.532 (6) and 0.468 (6) occupancy]. The carbamothioyl group is twisted by 63.6 (6) (mol-ecule A) and 80.3 (0)° (mol-ecule B) from the respective benzene ring. A strong intra-molecular N-H⋯O hydrogen bond occurs in each mol-ecule. The crystal packing is stabilized by weak inter-molecular N-H⋯O and N-H⋯S hydrogen-bond inter-actions, the latter forming an infinite co-operative hydrogen-bonded two-dimensional network along [110].
