A monoclinic polymorph of 1-benzoyl-4-thiobiuret
نویسندگان
چکیده
The title compound, C9H9N3O2S, is a monoclinic (C2/c) polymorph of the previously reported triclinic structure [Kang (2013 ▶). Acta Cryst. E69, o1327]. The mol-ecule is almost planar with an r.m.s. deviation of 0.069 Å from the mean plane of all non-H atoms. The benzoyl and terminal thio-urea fragments adopt a transoid conformation with respect to the central carbonyl O atom. Two intra-molecular N-H⋯O hydrogen bonds are present. In the crystal, N-H⋯O and N-H⋯S inter-actions link the mol-ecules into zigzag chains extending along the c-axis direction.

Second monoclinic form of (E)-3-(4-fluorophenyl)-1-phenylprop-2-en-1-one
The unit-cell dimensions and space group of the second monoclinic polymorph of the title compound, C15H11FO, differ from those of the previously reported form [Jing (2009 ▶). Acta Cryst. E65, o2515]. The title compound shows an E conformation of the C=C bond with the 4-fluoro-phenyl group opposite to the benzoyl group. The torsion angle of between the planes of the 4-fluoro-phenyl and benzoyl g...

The title compound, C(13)H(10)ClNO, (I), is a polymorph of the structure, (II), first reported by Gowda et al. [Acta Cryst. (2008), E64, o462]. In the original report, the compound crystallized in the ortho-rhom-bic space group Pbca (Z = 8), whereas the structure reported here is monoclinic P21/c (Z = 4). The principal difference between the two forms lies in the relative orientations of the ph...
