“…The grown crystal NNDPB and FNNDPB structures were confirmed by single‐crystal XRD analysis. The NNDPB crystal estimated to lattice parameters are a = 17.4490 (9) Å, b = 9.1998 (5) Å, c = 18.1264 (9) Å and in close agreement with the reported values . The FNNDPB crystal estimated to lattice parameters are a = 17.3659 (9) Å, b = 9.2238 (5) Å, c = 18.7491 (11) Å, and volume = 3003.2 (3) Å 3 .…”

“…It is clear that in both compounds de‐protonation takes place and also due to the shorter bond distances of C–N bond it was evident that both the compounds have high rotation barrier around the C–N bond. The tertiary aromatic amides are of special interest due to high rotation barrier around the C–N bond, which potentially gives different isomers of amide derivative and normally the C–N single bond distance = 1.47 Å …”

Nonlinear optical organic materials of N,N-diphenylbenzamide (NNDPB) and 4-fluoro-N,N-diphenylbenzamide (FNNDPB) are synthesized from benzoylation of N,N-diphenylamine using the substituted benzoyl chlorides. The single crystals of NNDPB and FNNDPB are grown by a slow evaporation technique. Single-crystal X-ray diffraction shows that both the crystals belong to orthorhombic crystallographic system with space group Pbca. Fourier transform infrared spectrum shows the chemical bonding and various functional groups, the carbonyl peak appeared at 1647 and 1651 cm −1 in NNDPB and FNNDPB compounds, respectively. 1 H and 13 C nuclear magnetic resonance analysis examines the placement of aromatic protons and carbons are identified to the synthesized materials. UV-vis near IR spectra analysis showed 100% transmission in the visible region for both NNDPB and FNNDPB crystals. As-grown crystal dielectric constant and dielectric loss are inversely proportional to the frequency at all the temperatures. The thermal properties of NNDPB and FNNDPB crystals are studied from thermogravimetric analysis/differential thermal analysis analysis, it is thermally stable up to 483 and 503 K. Crystal growth mechanism and defects are observed from etching studies. The relative second harmonic generation efficiency is measured by Kurtz-Perry powder technique and is found to be 1.55 and 1.7 times as that of potassium dihydrogen phosphate.

“…81 Although it is currently unknown as to precisely how the virus was transmitted from animals to humans, current research suggests that COVID-19 potentially was transmitted from bats to another susceptible animal, such as a pangolin 82 and then to a human. 83 Bats are frequently stored and sold in wet markets and are often transported alongside large groups of uncommon and illicitly traded animals that are consumed by humans. This form of transportation and storage allows the spread of pathogens between bats and different, sometimes exotic, and rare creatures that can carry and advance diseases under severe, stressful situations.…”

Illegal wildlife trade and wildlife trafficking are global environmental risks which is underscored not just by its convergence with other serious crimes but by the cross-border and trans-boundary nature of the crime, and its implications in many global health problems. The COVID-19 crisis, currently estimated to have been contracted from bats by humans through an intermediate host such as a pangolin, has propelled the global health implications of wildlife trade onto the global stage, thereby questioning global and national environmental governance structures to combat illegal wildlife trade and trafficking. Through a literature-based desk review, this paper appraises international environmental regulation such as the Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES); wildlife regulatory governance in Nigeria such as The Endangered Species (Control of International Trade and Traffic) Act and their implications in the current global pandemic. It finds that weak legal systems, lack of enforcement capacity, high corruption levels and insufficient coordination, knowledge, and capacity are among the critical drivers of this crisis. It recommends legal and policy prioritization and effective environmental governance with regards to combatting wildlife trafficking as a panacea for present and future pandemics.

Sterically crowded thioamides: deviations from planarity as determined by X-ray structure analyses and quantum chemical calculations

The structures of selected thiobenzamides and some corresponding benzamides with two more or less bulky N-substituents have been studied by single-crystal X-ray diffraction analyses. The planarity of the thioamide moiety, i.e., the internal rotation about the Ar-CS and the C-N bond as well as the bending of the two N-substituents versus the thioamide plane, was determined from the data. The experimental data were corroborated by quantum chemical calculations of molecular ensembles in the crystal and, in particular, by Hirshfeld surface analysis.
