Abstract top

The molecule of the title compound, [Pb(C14H14NS3)2], is located on a twofold rotation axis. The dithiocarbamate anion S,S'-chelates to the PbII atom, which shows a [Psi]-trigonal-bipyramidal coordination. The thiophene ring is disordered over two positions, the major component having 71.3 (7)% occupancy. The molecular conformation is stabilized by intramolecular C-H...S interactions.

Comment top

In continuation of our work on the crystal structure analysis of lead complexes, we have undertaken a single-crystal X-ray diffraction study for the title compound, and the results are presented here.

The X-ray study confirmed the molecular structure and atomic connectivity for (I), as illustrated in Fig. 1. The Pb atom is coordinated by four sulfur atom from two dithiocarbamate anions. The asymmetry in Pb-S bonds suggests that the lone pair on Pb(II) is stereochemically active. The geometry of this coordination PbS4 polyhedron is trigonal bipyramid. The geometry is similar to that reported for bis[N-benzyl-N-(2-phenylethyl)dithiocarbamato]lead(II) (Sathiyaraj et al., 2012).The superposition of the coordination polyhedron (PbS4) of (I) with this related reported structure, using Qmol (Gans & Shalloway, 2001) shows the r.m.s. deviation is 0.005 Å.

The sum of the angles at N1 [359.7°] is in accordance with sp2 hybridization. The thiophene ring is disordered over two positions, with a major component being 71.3 (7)%. The dihedral angles between the phenyl and the major and minor components of the thiophene ring are 74.8 (1) and 74.7 (1)°, respectively.

In addition to the van der Waals interactions, the molecular structure is influenced only by intramolecular C—H···S hydrogen bonds.

Experimental top

Benzyl(2-(thiophene-2-yl)ethyl)amine (4 mmol) and carbon disulfide (4 mmol) were dissolved in ethanol (20ml) and stirred for 30minutes. To this solution, an aqueous solution (100 ml) of Pb(NO3)2 (2 mmol) was added with constant stirring. A pale yellow powder precipitated that was filtered and dried. Single crystals of (I) were obtained by slow evaporation of dichloromethane and acetone (1:1) solution of the title compound at room temperature.

Refinement top

H atoms were placed in idealized positions and allowed to ride on their parent atoms, with C—H distances of 0.93-0.97 Å, and Uiso(H) = 1.2Ueq(C) for H atoms. The thiophene ring is disordered over two positions, with a major component being 71.3 (7)%. Pairs of C—S, C—C and C=C bond distances were restrained to 1.74 (1), 1.43 (1) and 1.37 (1) Å, respectively. The bond distances C3—C4 and C3—C4' were restrained to within 0.01 Å of each other. The temperature factors of C5' was set to those of S3 (as were these pairs: C4' to C4, S3' to C5, C6' to C6 and C7' to C7). The planarity of thiophene ring atoms were restrained to within 0.01 Å3 of each other. Pairs of C—S and C—C 1,3 bond distances were restrained to the values of 2.58 (1) and 2.33 (1) Å, respectively.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
