N′-Benzoyl-N,N-diethylthiourea: a monoclinic polymorph
نویسندگان
چکیده
In the crystal of the title compound, C(12)H(16)N(2)OS, inversion dimers linked by pairs of N-H⋯S hydrogen bonds occur, generating R(2) (2)(8) loops. The mol-ecules are also linked by weak C-H⋯O hydrogen bonds. The structure is isostructural with that of N'-benzoyl-N,N-diethyl-seleno-urea [Bruce et al. (2007 ▶). New J. Chem.31, 1647-1653].

A monoclinic polymorph of 1-benzoyl-4-thiobiuret
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-molecula...

The title compound, C(22)H(18)N(2)O(3) is the second monoclinic polymorph (P2(1)/c) of the compound, the first being reported in space group P2(1) [Bertolasi et al. (1993 ▶). J. Chem. Soc. Perkin Trans. 2, pp. 2223-2228]. In the mol-ecular structure of the title compound, the inter-planar angle between the benzoyl units is 80.04 (5)°, while the corresponding angles between the phenyl-hydrazinyl...

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...
