1,3-Bis(2-chloro-phen-yl)thio-urea: a monoclinic polymorph.

ABSTRACT: The title compound, C(13)H(10)Cl(2)N(2)S, represents a monoclinic polymorph of the previously reported ortho-rhom-bic form [Ramnathan et al. (1996 ?). Acta Cryst. C52, 134-136]. The mol-ecule is twisted with the dihedral angle between the benzene rings being 55.37?(7)°. The N-H atoms are syn to each other, which contrasts their anti disposition in the ortho-rhom-bic form. In the crystal, mol-ecules assemble into zigzag chains along the c axis via N-H?S hydrogen bonds. Chains are connected into layers via C-H?Cl inter-actions, and these stack along the a axis.

1,3-Bis(3-methyl-phen-yl)thio-urea: triclinic polymorph.

Project description:The title compound, C(15)H(16)N(2)S, crystallizes with two molecules in the asymmetric unit. The crystallographic behaviour of the two isomers is different. The mol-ecules are dimerized, forming an R(2) (2)(8) ring motif due to inter-molecular N-H?S hydrogen bonds. C-H?S hydrogen bonds form R(2) (2)(12) ring motifs. In one molecule, the dihedral angle between the benzene rings is 62.54?(6)°, whereas in the other it is 79.54?(6)°. The H atoms of one of the methyl groups in each molecule are disordered over two sites, with occupancy ratios of 0.52?(3):0.48?(3) and 0.60?(3):0.40?(3).

1,3-Bis(2-meth-oxy-phen-yl)thio-urea.

Project description:In the title compound, C(15)H(16)N(2)O(2)S, the N-C(=S) bond lengths are indicative of the presence of amide-type resonance. The dihedral angles between the thio-urea unit and the attached aromatic rings are 59.80 (5) and 73.41 (4)° while the dihedral angle between the rings is 56.83 (4)°. In the crystal, inversion dimers linked by pairs of N-H⋯S hydrogen bonds occur. An N-H⋯π inter-action is observed for the second amino group. The shortest centroid-centroid distance between two aromatic systems is 4.0958 (8) Å.

A new polymorph of 1,3-bis-(penta-fluoro-phen-yl)urea.

Project description:The title compound, C13H2F10N2O, has been previously described in the space group Pbca with Z = 8 [Jai-nhuknan et al. (1997 ▶). Acta Cryst. C53, 455-457]. The current P212121 polymorph was obtained from a tetra-hydro-furan solution. The penta-fluoro-phenyl rings make dihedral angles of 50.35 (6) and 54.94 (6)° with the urea fragment, in close accord with those reported for the first polymorph. In the crystal, both of the N-H groups donate H atoms to the same carbonyl O atom, forming a one-dimensional mol-ecular array along the a axis. There are close contacts between perfluoro-phenyl C atoms within the array [3.228 (3) Å] and halogen bonds are also observed between the arrays [F⋯F = 2.709 (2) and 2.7323 (18) Å].

A monoclinic polymorph of N-(3-chloro-phen-yl)benzamide.

Project description: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 phenyl and benzene rings [dihedral angle = 8.90 (13)° for (I) and 61.0 (1)° for (II)]. The inclination of the amide -CONH- units to the benzoyl ring is more similar [15.8 (7)° for (I) and 18.2 (2)° for (II)]. In both forms, the N-H bonds are anti to the 3-chloro substituents of the aniline rings. In the crystal, inter-molecular N-H⋯O hydrogen bonds form C(4) chains along c. These chains are bolstered by weak C-H⋯O inter-actions that generate R(2) (1)(6) and R(2) (1)(7) ring motifs.

1-(3-Chloro-phen-yl)thio-urea.

Project description:In the title compound, C(7)H(7)ClN(2)S, the thio-urea N-C(=S)-N plane forms a dihedral angle of 64.80?(6)° with the benzene ring. In the crystal, mol-ecules are linked via inter-molecular N-H?S and N-H?Cl hydrogen bonds into a sheet extending parallel to the (101) plane.

1-(4-Chloro-butano-yl)-3-(3-chloro-phen-yl)thio-urea.

Project description:The two independent mol-ecules in the asymmetric unit of the title compound, C11H12Cl2N2OS, exhibit different conformations, with the benzene ring and the N2CS thio-urea group forming dihedral angles of 87.40?(18) and 69.42?(15)°. An intra-molecular N-H?O hydrogen bond is present in each mol-ecule. Two further N-H?O hydrogen bonds link the independent mol-ecules into a dimer. In the crystal, the dimers are linked by N-H?S and C-H?S hydrogen bonds, forming chains parallel to the c axis.

1-(4-Chloro-butano-yl)-3-(2-chloro-phen-yl)thio-urea.

Project description:The asymmetric unit of the title compound, C(11)H(12)Cl(2)N(2)OS, contains two crystallographically independent mol-ecules with different conformations: the benzene ring and the thio-urea fragment form dihedral angles of 74.32 (11) and 89.39 (11)°. One amino group in each mol-ecule is involved in intra-molecular N-H⋯O and inter-molecular N-H⋯O hydrogen bonding: the latter links pairs of independent mol-ecules into dimers. In the crystal, weak N-H⋯S inter-actions link these dimers into chains propagating along the c axis.

3-Acetyl-1-(3-chloro-phen-yl)thio-urea.

Project description:In the title compound, C(9)H(9)ClN(2)OS, the 3-chloro-phenyl and acetyl-thio-urea fragments are oriented at a dihedral angle of 62.68?(5)°. An intra-molecular N-H?O hydrogen bond generates an S(6) ring motif. Mol-ecules are linked into dimers via a cyclic R(2) (2)(8) motif of N-H?S hydrogen bonds. These dimers are further connected through C-H?S inter-actions, completing an R(2) (2)(12) motif, into chains along [010].

A new monoclinic polymorph of 1,1'-bis-(di-phenyl-thio-phosphor-yl)ferrocene.

Project description:The title compound, [Fe(C17H14PS)2], is a second monoclinic polymorph (P21/c, with Z' = 1) of the previously reported monoclinic (C2/c, with Z' = 1/2) form [Fang et al. (1995 ▸). Polyhedron, 14, 2403-2409]. In the new form, the S atoms lie to the same side of the mol-ecule with the pseudo S-P⋯P-S torsion angle being -53.09 (3)°. By contrast to this almost syn disposition, in the C2/c polymorph, the Fe atom lies on a centre of inversion so that the S atoms are strictly anti, with a pseudo-S-P⋯P-S torsion angle of 180°. The significant difference in mol-ecular conformation between the two forms does not result in major perturbations in the P=S bond lengths nor in the distorted tetra-hedral geometries about the P atoms. The crystal packing of the new monoclinic polymorph features weak Cp-C-H⋯π(phen-yl) inter-actions consolidating linear supra-molecular chains along the a axis. These pack with no directional inter-actions between them.
