Bromidobis(N,N′-diphenyl­thio­urea-κS)copper(I) monohydrate

In the title compound, [CuBr(C13H12N2S)2]·H2O, the CuI atom adopts a slightly distorted trigonal-planar coordination arising from two S atoms of two diphenyl­thio­urea ligands and a bromide ion. There are two intra­molecular 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⋯π inter­actions. There also exist π–π inter­actions with a distance of 3.876 (2) Å between the centroids of benzene rings of two different ligands. Together, the inter­molecular inter­actions lead to a three-dimensional network

(E)-1-(4-Meth­oxy­benzyl­idene)-2-phenyl­hydrazine

In the title compound, C14H14N2O, the dihedral angle between the aromatic rings is 9.30 (6)°. In the crystal, mol­ecules are linked by C—H⋯π and N—H⋯π inter­actions

(E)-1-(2-Nitro­benzyl­idene)-2-phenyl­hydrazine

The asymmetric unit of the title compound, C13H11N3O2, contains two mol­ecules with slightly different conformations: the dihedral angle between the aromatic rings is 13.01 (10)° in one mol­ecule and 14.05 (10)° in the other. Both mol­ecules feature short intra­molecular C—H⋯O contacts, which generate S(6) rings. In the crystal, both mol­ecules form inversion dimers linked by pairs of N—H⋯O hydrogen bonds, thereby generating R 2 2(16) rings

Dichloridobis(N,N′-diethylthiourea-κS)mercury(II)

There are two molecules in the asymmetric unit of the title compound, [HgCl2(C5H12N2S)2]. In both molecules, the N,N′-diethylthiourea ligands exhibit a cis,trans geometry around their C—N amide bonds. The shapes of the molecules are, to a large extent, determined by intramolecular N—H...Cl hydrogen bonds formed by the N—H groups from the cis amide groups. In one molecule, these groups are involved in three-center hydrogen bonds involving both chloride ligands, whereas in the other molecule only one Cl ligand takes part in intramolecular hydrogen bonding. The coordination around the Hg atom is distorted tetrahedral with an S2Cl2 donor set. Intermolecular hydrogen bonds between N—H groups from the trans amide units of the thioamide ligands and the chloride ligands connect the molecules into a polymeric chain extending along the c axis. One of the ethyl groups of the N,N′-diethylthiourea ligands is disordered over two positions in one of the molecules, with an occupancy of 0.654 (17) for the major component

Crystal structures of [Hg(N-ethylthiourea)(2)(CN)(2)] and [Hg(N-propylthiourea)(2)(CN)(2)]

Two mercury(II) cyanide complexes of N-ethylthiourea (Ettu) and N-propylthiourea (Prtu) ligands, [Hg(Ettu)(2)(CN)(2)] (1) and [Hg(Prtu)(2)(CN)(2)] (2), were prepared and their crystal structures were determined by X-ray crystallography. In both structures, the mercury atom is coordinated to two sulfur atoms of thioureas and two cyanide carbon atoms in a pseudo-tetrahedral mode with the bond angles in the range of 90.52(11)-162.2(3)A degrees. The structures are stabilized by N-H-S, N-H-N, and C-H-N intramolecular and intermolecular hydrogen bonds

(E)-1-(4-Chlorobenzylidene)-2-phenylhydrazine

The asymmetric unit of the title compound, C13H11ClN2, contains two geometrically distinct molecules; one molecule is close to planar [dihedral angle between the aromatic rings = 2.44 (18)°] and the other is twisted about the linking hydrazide group [dihedral angle = 14.08 (19)°]. In the crystal, the N—H groups do not form hydrogen bonds and the molecules are linked by weak C—H...π interactions
