چکیده
The title compound, C(8)H(7)BrO, is a halogenated derivative of acetophenone. The mol-ecule shows noncrystallographic C(s) symmetry. The intra-cyclic C-C-C angles cover the range 118.8 (2)-120.4 (3)°. In the crystal structure, C-H⋯O contacts connect the mol-ecules into undulating sheets perpendicular to the crystallographic c axis.

In the title thio-semicarbazone derivative, C(9)H(10)N(4)OS·H(2)O, intra-molecular N-H⋯N hydrogen bonds result in the formation of two nearly coplanar five- and six-membered rings, which are also almost coplanar with the adjacent phenyl ring. The oxime group has an E configuration and is involved in inter-molecular O-H⋯O hydrogen bonding as a donor. In the crystal structure, intra-molecular O-H...
