Bis[benzyl 3-(3-phenylprop-2-enylidene)dithiocarbazato-κ²N³,S]cadmium

Abstract

In the title complex, [Cd(C17H15N2S2)2], the CdII ion is located on a twofold rotation axis and exhibits a coordination number of four within a very distorted coordination environment that is best described as bis­phenoidal. The two deprotonated Schiff base ligands chelate the CdII ion through the azomethine N and the thiol­ate S atom. The dihedral angle between the two chelating ligands is 84.01 (9)°. Weak inter­molecular C—H⋯S inter­actions lead to the formation of chains along the c axis.

“…For background to related Schiff bases of S-substituted dithiocarbazates with cinnamaldehyde, see: Tarafder et al (2008Tarafder et al ( , 2010. For the corresponding metal complexes, see: Reza et al (2012); Liu et al (2009). For the biological activity of similar sulfur-nitrogen-containing Schiff base derivatives, see: Maia et al (2010); Pavan et al (2010); Zhu et al (2009).…”

“…Schiff bases of S-substituted dithiocarbazates with cinnamaldehyde attract interest in terms of both coordination chemistry (Reza et al, 2012;Liu et al, 2009) and for their biological activities (Maia et al, 2010;Pavan et al, 2010;Zhu et al, 2009. In pursuing our continuing interest in the coordination chemistry of dithiocarbazate derivatives and their biological importance (Tarafder et al, 2010;Tarafder et al, 2008), the title compound, (I), the product of condensation between S-4-picolyl dithiocarbazate and cinnamaldehyde, was investigated.…”

Preparation of 5‐Substituted‐1H‐Tetrazoles Catalyzed by MOFs via Two Strategies: Direct Condensation of Aryl Nitriles with Sodium Azide, and Tri‐Component Reaction Method

“…[11] Although this procedure was simple enough, but using homogenous Zn (II) salts brought its own problem in separating of heavy metal at the end of the reaction, especially in industrial scale. In recent years, many homo-and heterogeneous catalysts have been used for this purpose such as silica sulfuric acid, [12] Mw À Pd/Co@CNT NPs, [13] Fe 3 O 4 @SiO 2 -TCT-PVAÀ Cu(II), [14] Pt-NPs@VC, [15] Zn hydroxyapatite, [16] Zn/Al hydrotalcite, [17] Cu 2 O, [18] diisopropylethylammonium acetate, [19] Fe(OAc) 2 , [20] CdCl 2 , [21] SiO 2 -H 3 BO 3 , [22] Cu-MCM-41, [23] Pd-SBT@MCM-41, [24] CuO nanoparticles, [25] copper (I) chloride, [26] [Cu(phen)(PPh 3 ) 2 ]NO 3 [27] and so on. [28] Although in many of these reported catalysts, the desired products were formed, but a number of them have some drawbacks such as prolonged reaction time, moderate yield, homogeneous or non-scalable catalyst and problem in their reusability.…”
