density gradient (NCI-RDG) analyses, were pursued to generate a profound understanding of the structure-directing interactions in these complexes. The supramolecular assemblies are first driven by cooperative π⋯π interactions and hydrogen bonds followed by CH⋯π, S⋯S and S⋯π linkages. In the case of the linkage isomers, intermolecular interactions may have a significant role in the formation of the less

carbohydrazone ligands with different positions between functional groups of –NNHC(O)– and Npy (ortho-, meta- and para-) have been applied for the synthesis of cuprous halide complexes. X-ray crystallography reveals that the ortho analogous ligand, Lo, functions in a chelating mode, adopting a mononuclear structure in complex Co, [CuClLoPPh3], while the meta and para analogs, Lm and Lp, act as ambidentate ligands
在–NNHC(O)–和N py(邻-,间-和对-)官能团之间具有不同位置的吡啶基碳氢hydr配体已用于合成卤化亚铜配合物。X射线晶体学分析表明,邻位相似配体L o以螯合模式起作用,在复杂C o [CuClL o PPh 3 ]中采用单核结构,而间位和对位类似物L m和L p起作用作为歧义配体,通过N进行配位卤素桥联的双核络合物[Cu(μ-X)LPPh 3 ] 2中的py原子(X = Cl,Br,I和L = L m, L p)。非共价分子间相互作用对最终结构组装的影响已通过几何和Hirshfeld分析进行了讨论。此外,在实验和理论上都研究了配合物的光物理性质。这项研究考虑了配体结构和卤化物变化对复合物的结构和光物理方面的影响。

A systematically generated series of hydrazones were analyzed as potential inhibitors of anthrax lethal factor. The hydrazones were screened using one UV-based and two fluorescence-based in vitro assays. The study identified several inhibitors with IC50 values in the micromolar range, and importantly, significant differences in the types of inhibition were observed with the different assays.

Synthesis, structural characterization, and molecular docking studies of bioactive bismuth(III) complexes with substituted hydrazones
4-hydroxybenzhydrazide, thiophene-2-carboxylic acidhydrazide, 3-hydroxy-2-naphthoic acidhydrazide, Isonicotic acidhydrazide and appropriate aromatic aldehydes like pridine-2-carboxaldehyde and quinoline-2-carboxyaldehyde. These hydrazones (ligands),then complexed to Bi(III) species to yield the target compounds. They were characterized by FTIR, and NMR spectroscopy to find out an explicit evidence about
