Diverse Self-Assembled Molecular Architectures Promoted by C-H···O and C-H···Cl Hydrogen Bonds in a Triad of α-Diketone, α-Ketoimine, and an Imidorhenium Complex: A Unified Analysis Based on XRD, NEDA, SAPT, QTAIM, and IBSI Studies.

X-ray structural elucidation, supramolecular self-assembly, and energetics of existential noncovalent interactions for a triad comprising α-diketone, α-ketoimine, and an imidorhenium complex are highlighted in this report. Molecular packing reveals a self-assembled 2D network stabilized by the C-H···O H-bonds for the α-diketone (benzil), and the first structural report of Brown and Sadanaga stressing on the prevalence of seems to be an oversimplified conjecture. In the α-ketoimine, the imine nitrogen atom undergoes intramolecular N···H interaction to render itself inert toward intermolecular C-H···N interaction and exhibits two types of C-H···O H-bonds in consequence to generate a self-assembled 2D molecular architecture.

Noncovalent and Covalent O-H···O Interactions in PPhO Cocrystals: A Correlation Study Involving QTAIM, SAPT, NBO, and IBSI Methods.

PPhO.hemihydrate polymorphs and 11 assorted PPhO cocrystals collectively constitute a reliable stock to pursue a systematic analysis aiming to investigate the impacts of some vital issues on the TPPO.H-bond donor aggregates.
