“…And the peaks at visible region at (837 nm=11947 cm -1 ) and (937nm=10672 cm -1 ) due to the d-d electronic transition. These peaks are assigned to ( 3 A 2 g→ 3 T 1 g (P) ) and ( 3 A 2 g→ 3 T 2 g (F) ) respectively, transitions confirming an octahedral structure around Ni (II) ion complex [32]. "The magnetic susceptibility measurement for the solid Ni(II) complex is (2,9) B.M.…”

New bidentate dithiocarbamate ligand (NaL) namely . To characterize the ligand and its complexes, used different analyses methods such FTIR, UV-Vis, elemental microanalysis, atomic absoreption, magnetic susceptibility, conductance, melting points, 1 H-13 C-NMR spectroscopy, thermal analysis and mass spectrum. These studies indicated the formation of DTC complexes which their geometries about metal centers are octahedral; except Pd-complex is square planer. The bacterial activity evaluation against investigated bacterial species indicated that the metal complexes are more active than the free ligand when compared them.

“…[19][20][21][22][23] Within the dithiocarbamate function, the C-N dtc bond lengths in the range 1.318(9)-1.349(9) Å indicate a substantial delocalization of π-electron density in this bond. [14][15][16][17][18] The crystal structure of 1 is further stabilized through two C-H⋅⋅⋅F interactions (Figure 4). Intramolecular weak C-H⋅⋅⋅S interactions are present in this compound which can be seen in Figure S15.…”

“…[6][7][8][9][10] Interest in organotin dithiocarbamate complexes arises because of their variety of structures and wide range of applications in fields such as agriculture, biology, organic synthesis and catalysis. [11][12][13] The products obtained from the reaction of organtin(IV) halides with dithiocarbamates show substantial tendency to generate self-assembled supramolecular architectures [14,15] and can also offer a platform for the formation of macrocyles [16][17][18] due to the Lewis acidity of organotin(IV) chlorides. In terms of crystallographic analyses, the diorganotin(IV) dithiocarbamates are the best studied and arguably the most interesting in terms of the observed structural diversity.…”

Four new macrocyclic dinuclear dibutyltin(IV) dithiocarbamate complexes of the type [Bu2Sn(dtc)]2, where dtc = hexane‐1,6‐diylbis(4‐fluorobenzyldithiocarbamate) anion (1), hexane‐1,6‐diylbis(4‐chlorobenzyldithiocarbamate) anion (2), hexane‐1,6‐diylbis(furfuryldithiocarbamate) anion (3) and hexane‐1,6‐diylbis(pyrrole‐2‐ylmethyldithiocarbamate) anion (4), have been prepared. The dithiocarbamate ligands efficiently self‐assemble with Bu2Sn(IV) to form bimetallic 26‐membered macrocycles. All the complexes have been characterized using elemental analysis, infrared and NMR (1H and 13C) spectroscopies and X‐ray crystallography. Single‐crystal X‐ray diffraction analysis of all the complexes confirms the formation of the dinuclear metallomacrocycles in which dithiocarbamate ligands are asymmetrically bound to the tin atoms. The coordination sphere around the tin atom in 1–4 can be described as a skew trapezoidal bipyramid. The dimensions of the cavity of the macrocycles of 1–4 are ca 8.0 × 9.0 Å2. Complexes 1–4 were evaluated for their in vitro anticancer activity against MCF‐7 and HL‐60 cells. Complexes 1 and 2 are more active against MCF‐7 and HL‐60. Thermal decomposition of 1 and 4 yielded tin sulfides. They were characterized using powder X‐ray diffraction (PXRD), high‐resolution transmission electron microscopy and UV diffuse reflectance and energy‐dispersive X‐ray spectroscopies. PXRD studies reveal that the as‐prepared tin sulfides are composed of orthorhombic phase of SnS.

Four new carbamates (RZ1–RZ4) were synthesized from different amine moieties through reported methods. The reaction was monitored using thin layer chromatography and characterization was done using m.p., fourier‐transform infrared spectroscopy (FTIR), and X‐ray diffraction (XRD) techniques. Density functional theory (DFT) studies were carried out using Gaussian 09 software to compare the theoretical and practical parameters of the synthesized compounds. Highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) were also drawn to calculate the energy difference between orbitals. In‐vitro enzyme inhibition potential against acetylcholine esterase (AChE), butyrylcholine esterase (BChE), and protease was checked through standard protocols that suggested moderate inhibition against selected enzymes. Docking studies were also carried out, which depicted that these compounds have ability to bind on the active site of AChE and BChE.
