were added consecutively with stirring at room temperature. The reaction mixture was stirred for about 30 min. The product was collected by filtration and washed with methanol to afford ared precipitate. This precipitate was purified by recrystallization from acetone in air and then dissolved in acetone again. The solution was left to stand for several days at approximately 293 K, and plate-like, red crystals suitable for the X-ray structure determination were obtained. UV data are available in the CIF. Experimental detailsAll Ha toms placed in geometrically calculated positions and refined using ariding model with U iso (H) =1.2 or 1.5 U eq (C). The high residual values are attributed to the poor quality of the crystal. DiscussionSince their discovery nearly three decades ago, metal bis(2-thioxo-1,3-dithiole-4,5-dithiolate) (dmit) complexes have attracted increasing attention owing to their potential applications as precursors for electrical conductors, superconductors [2] and for their optical and photoelectrical properties [3]. Furthermore, many of these complexes have been reported as promising nonlinear optical materials [4]. Among them, many of Ni-dmit complexes have been synthesized and studied for optical applications and their crystal structures have been reported. However, there are only af ew of research on the crystal structure and optical properties of the analogous, Pd-dmit complexes. The crystal structure of the title compound shows some similarities with most of the previously reported structures of related Pddmit complexes. The dmit ligand behaves typically as abidentate ligand and coordinates the Pd 2+ ion through vicinal exocyclic sulfur atoms of two dmit molecules in aquasi square-planar geometry ( figure, top). The two five-membered rings formed by the metal ion and its adjacent atoms have an dihedral angle of 0.0(2)°a nd the maximum deviation from the least-squares plane of [Pd(dmit) 2 ] 2-is 0.179(4) Å for S1 and the mean deviation is 0.104 . Å.The bond-lengths of dmit ligand show typical conjugation characters. The C=S double bond (1.653(9) Å)ismuch longer than that of typical C=S (1.599 Å) [5]. The other C-Sbonds span the range of 1.705(10) to 1.770(7) Å.T hey are all shorter than the typical C-Ssingle bond (1.819 Å)and are essentially Z. Kristallogr. NCS 225 (2010) 131-133

The third-order nonlinear optical properties of the 1,1'-Methylenedipyridinium bis[tetrachloridoaurate(III)] Dimethyl sulfoxide (DMSO) have been studied using Z-scan technique. Measurements were performed with a CW diode laser at 635 nm wavelength and 16.4 mW power.The nonlinear optical absorption coefficient (β) and nonlinear refraction (n 2 )were found at 7.45×10 -4 cm/W and 1.08×10 -8 cm 2 /W, respectively. The nonlinear absorption coefficient β decrease with increase in on-axis input intensity I 0 . The cross-section of the excited state (σ ex ) was found to be larger than the cross-section of the ground state (σ g ). This feature confirmed that the reverse saturable absorption (RSA) mechanism was responsible for the optical limiting effect. The results suggest that this material is considered as a promising candidate for future optical devices applications.

“…Furthermore, many of these complexes have been reported as promising nonlinear optical materials [4]. Zn complexes of dmit are promising organic optical materials, because the Zn complex anions effectively promote photoelectric properties and second harmonic generation by replacing the iodide in hemicyanine [5].…”

Source of materialThe synthesis of the title compound involved amodification of literature methods [ 1]. CS 2 (24 ml) was added to degassed dimethyl formamide (DMF, 48 ml), and the mixturewas cooled to 273 K. Sodium (1.45 g) was added to the solution and the mixture was vigorously stirred under cooling until the reaction was completed. Several ml of MeOH were slowly added. To this solution, separate solutions of (i) ZnCl 2 · 2H 2 O(2.13 g) dissolved in 25-28% NH 3 (40 ml) and (ii) Bu 4 NBr (10.12 g) in water (30 ml) were added consecutively with stirring at room temperature. The mixture was stirred overnight. The product was isolated by filtration, washed with water and MeOH, and then solved in acetone. Single crystals of the title compound used for X-ray structure analysis were obtained by evaporation of acetone from the solution held at room temperature. Experimental detailsAll Ha toms were placed in geometrically calculated positions and refined using ariding model with U iso(H) =1.2 Ueq(C). 2-anion has C 2 symmetry with the Zn(II) ion located on the twofold axis. The dmit ligand shows its typical behaviour as abidentate ligand and coordinates the Zn 2+ ion through vicinal exocyclic sulfur atoms of two dmit molecules in adistorted tetrahedral manner. The bond lengths of dmit ligand show typical conjugation character. The C=S double bond (1.666(3) Å)ismuch longer than that of typical C=S (1.599 Å) [10]. The other C-S bonds span the range of 1.709(3) to 1.74 Å (1.819 Å)a nd are essentially single bonds with some double-bond character. The C=C bond lengths of the dmit ion are 1.359(3) Å and very close to the corresponding double-bond value of 1.34 Å.T he S-Zn-S bond angles range from 95.12(2)°to 123.93(4)°.The Zn-Sbond lengths are 2.3391(7) Å and 2.3435(7) Å,respectively. In the crystal packing of the compound, the intermolecular contacts are consistent with avan der Waals type of packing and the structure displays no sizable intermolecular voids. The packing is formed by channels of cations and anions viewing along [010]. Discussion
