Hirshfeld surface analysis has been widely used in recent years as a means to quantify and visualize various types of intermolecular interactions molecular crystals. This review article introduces discussed with 2D fingerprint plots. In addition, using CIF files obtained from our previous results, was newly performed, the resulting 3DHirshfeld surfaces, print plots, structural features, crystal structure relationships were described. Classification their interactions, statistical discussion...
Photoinduced magnetization of the cyano-bridged 3d-4f heterobimetallic assembly Nd(DMF)4(H2O)3(mu-CN)Fe(CN)5.H2O (1) (DMF = N,N-dimethylformamide) is described in this paper. The chiMT values are enhanced by about 45% after UV light illumination temperature range 5-50 K. We propose that induces a structural distortion 1. This small change propagated molecular interactions inorganic network. Furthermore, cooperativity resulting from interaction functions to increase activation energy...
The rain tree, or Samanea saman (Family Fabaceae), grows medium-to-large.Its anti-inflammatory, antioxidant, and anti-microbial properties make it a leading medicine in Ayurveda for numerous diseases.The current study explored the pharmacognostic, physicochemical, phytochemical qualities of S. leaf.The pharmacognostic assessment examined leaf morphology microscopy.Physicochemical characteristics include analysis ash, extractives, moisture, organic foreign matter, dry bulk density.Microscopic...
This paper uses deep learning to present a proof-of-concept for data-driven chemistry in single-molecule magnets (SMMs). Previous discussions within SMM research have proposed links between molecular structures (crystal structures) and magnetic properties; however, these only interpreted the results. Therefore, this study introduces approach predict properties of using learning. The deep-learning model learns structural features molecules by extracting from 3D coordinates presented paper....
The influence of substituents at the C2carbon N1-substituted thiosemicarbazones, {C4H3X–C2(CH3)N3–N2H–C1(S)N1HR2} (X = O, S) on geometry nickel(II) complexes has been investigated. presence a methyl group C2 position 2-acetylfuran-N1-substituted thiosemicarbazones {(C4H3O)–C2(CH3)N3–N2H–C1(S)N1HR2, R2 CH3, HaftscN–Me; C2H5, HaftscN–Et; C6H5, HaftscN–Ph} induces unusual coordination by furan ring and yielded high spin octahedral complexes, [Ni(κ3-O, N3, S-aftscN–R2)2], CH31, C2H52,...
The extrinsic catalytic properties of the laccase enzyme enable it to oxidize a wide range metallic compounds, making an essential for producing biofuel.We have employed computational and experimental approaches while searching cathode materials biofuel cells composed various metal complexes.Laccase is oxygenreducing copper enzyme.In this present study, we focused on complicated hybrid systems enzymes complexes, which are quite different from singlecomponent system complexes.We obtained...
We prepared L -amino acids ( -valine and -serine, respectively) based on the Schiff base Cu 2+ complexes CuSV CuSS in absence/presence of hydroxyl groups their imidazole-bound compounds CuSV-Imi CuSS-Imi to reveal effects SOD activity. The structural spectroscopic features were evaluated using X-ray crystallography, UV-vis spectroscopy, EPR spectroscopy. behavior upon addition lysozyme indicated that both coordinated by imidazole group His15 at equatorial position, leading formation hybrid...
This paper reports the generation of microdroplets on a water-repellent device equipped with an array tiny umbrella-shaped pillar structures.
In this study, single crystals of previously reported Schiff base copper (II) (Cu) and nickel (Ni) complexes were synthesized; a structural analysis was performed using data measured at high temperatures, 298 K 410 K; CIF electron density maps obtained. The purpose study to examine the accuracy high-temperature measurements in X-ray crystal structure analyses details atomic movement. Various (statistics such as standard deviation) obtained from analysis, lattice constants, temperature...
The title complex, [Zn(C 11 H NO 4 )(C 3 N 2 )(H O)], which includes a tridentate ligand, was synthesized from L-threonine and salicylaldehyde. One water molecule one imidazole additionally coordinate the zinc(II) center in distorted trigonal–bipyramidal geometry. crystal structure features N—H...O O—H...O hydrogen bonds. A Hirshfeld surface analysis indicates that most important contributions to packing are H...H/H...H (50.7%) O...H/H...O (25.0%) contacts.
Photofunctional magnetic vesicles of spiropyran (SP1822) that contain iron oxide particles, which exhibit super-paramagnetic properties at room temperature, were prepared. Photoinduced aggregation the was observed by UV illumination. As a result, we able to increase magnetization value photoillumination temperature.
