The crystal structure features numerous N-H?O, N-H?N, O-H?O and O-H?N hydrogen bonds. Two O atoms of a sulfate anion were found to be disordered over two orientations in a 0.620?(9):0.380?(9) ratio. The crystal studied was a racemic twin with BASF = 0.17?(5).

Bromidobis(N,N'-diphenyl-thio-urea-?S)copper(I) monohydrate.

Project description:In the title compound, [CuBr(C(13)H(12)N(2)S)(2)]·H(2)O, the Cu(I) atom adopts a slightly distorted trigonal-planar coordination arising from two S atoms of two diphenyl-thio-urea ligands and a bromide ion. There are two intra-molecular N-H?Br hydrogen bonds completing twisted six-membered rings with R(6) motifs. The dihedral angles between the aromatic rings in the ligands are 62.11?(13) and 85.73?(13)°. In the crystal, components are linked by N-H?O, O-H?S and O-H?? inter-actions. There also exist ?-? inter-actions with a distance of 3.876?(2)?Å between the centroids of benzene rings of two different ligands. Together, the inter-molecular inter-actions lead to a three-dimensional network.

Bis-(N,N'-diphenyl-thio-urea)iodido-copper(I) monohydrate.

Project description:In the title compound, [CuI(C(13)H(12)N(2)S)(2)]·H(2)O, each Cu(I) ion is coordinated by two S atoms [Cu-S 2.2282?(16), 2.2377?(15)?Å] from two N,N'-diphenyl-thio-urea ligands and one iodide ion [Cu-I 2.5170?(11)?Å] in a trigonal planar geometry.

Dichloridobis(thio-urea-?S)nickel(II).

Project description:The title complex, [NiCl(2)(CH(4)N(2)S)(2)], has been synthesized from the previously reported (diamino-methyl-idene)sulfonium chloride-thio-urea (3/2) salt [Zouihri (2012b ?). Acta Cryst. E68, o257]. The Ni(II) ion is coordinated in a distorted tetra-hedral geometry by two mol-ecules of thio-urea [Ni-S = 2.3079?(7) and 2.3177?(6)?Å] and two chloride anions [Ni-Cl = 2.2516?(7) and 2.2726?(7)?Å]. The bond angles at the Ni atom lie between 96.69?(2) and 115.40?(3)°, while the dihedral angle between the mean planes of the two thio-urea ligands is 6.36?(15)°. The crystal structure is characterized by intra- and inter-molecular N-H?Cl hydrogen bonds, which lead to the formation of two-dimensional networks lying parallel to the ab plane. The networks are linked via classical N-H?Cl and N-H?S hydrogen bonds, forming a three-dimensional arrangement.

N-Benzoyl-N'-(1,10-phenanthrolin-5-yl)thio-urea dichloro-methane hemisolvate monohydrate.

Project description:The title compound, C(20)H(14)N(4)OS·0.5CH(2)Cl(2)·H(2)O, contains 1,10-phenanthroline and benzoyl fragments that adopt cisoid and transoid conformations respectively, with respect to the S atom. In the crystal, mol-ecules are linked by inter-molecular O-H?O, O-H?N, N-H?O and C-H?O hydrogen bonds, forming chains along [011]. Weak C-H?? and slipped ?-? stacking inter-actions [centroid-centroid distances = 3.715?(3), 3.684?(3) and 3.574?(2)?Å] are also observed. In addition to an ordered water mol-ecule of solvation, there is a disordered dichloro-methane solvent mol-ecule which was difficult to model correctly. The contributions to the electron density for this mol-ecule was removed using the SQUEEZE procedure in PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155].

Crystal structure of bis-(thio-cyanato-?S)bis-(thio-urea-?S)mercury(II).

Project description:In the title complex, [Hg(NCS)2(CH4N2S)2], the Hg(II) atom is four-coordinated having an irregular four-coordinate geometry composed of four thione S atoms of two thio-cyanate groups and two thio-urea groups. The S-Hg-S angles are 172.02?(9)° for the trans-thio-cyanate S atoms and 90.14?(5)° for the cis-thio-urea S atoms. The mol-ecular structure is stabilized by an intra-molecular N-H?S hydrogen bond, which forms an S(6) ring motif. In the crystal, mol-ecules are linked by a number of N-H?N and N-H?S hydrogen bonds, forming a three-dimensional framework. The first report of the crystal structure of this compound appeared in 1966 [Korczynski (1966 ?). Rocz. Chem. 40, 547-569] with an extremely high R factor of 17.2%, and no mention of how the data were collected.
