N-(4-Chlorobutanoyl)-N′-phenylthiourea

Abstract

The asymmetric unit of the title compound, C11H13ClN2OS, contains two independent mol­ecules. Both mol­ecules maintain a trans–cis configuration with respect to the position of the carbonyl group and the benzene ring against the thione group across the C—N bonds. The mol­ecules are stabilized by intra­molecular N—H⋯O hydrogen bonds. In the crystal, the mol­ecules are linked by inter­molecular N—H⋯S, N—H⋯O and C—H⋯S hydrogen bonds into chains along the c axis. C—H⋯π inter­actions further stabilize the crystal structure.

N-(4-Bromobutanoyl)-N′-phenylthiourea

“…The title compound (I) is similar to previously reported N-(4-chlorobutanoyl)-N′-phenyl thiourea (Yamin et al, 2011), except the chlorine atom is replaced by bromine atom. The asymmetric unit also consists of two independent molecules linked by N-H•••O hydrogen bonds forming a pseudo dimer (Fig.…”
