In the recent publication by Zhou et al. [(2025). IUCrJ, 12, 16–22], crystal structure of benzo[a]pyrene was studied under high pressure up to 28 GPa using single-crystal X-ray diffraction and DFT calculations. This commentary highlights importance for analyzing organic molecular crystals.
Four secondary diamines with aromatic spacer groups derived from α,α′‐dibromo‐ p ‐xylene and 4,4′‐bis(chloromethyl)‐1,1′‐biphenyl have been transformed into bis‐dithiocarbamate ligands each combined dimethyl‐, di‐ n ‐butyl‐, diphenyltin(IV) dichloride to yield a total of 12 mononuclear diorganotin(IV) complexes six‐coordinate metal coordination geometries either 23‐ or 27‐membered macrocyclic structures. The products were fully characterized by IR NMR ( 1 H, 13 C, 119 Sn) spectroscopy...
Abstract Di‐ and trinuclear organotin(IV) complexes, in which the metal atoms are separated by large aromatic connectors, useful building blocks for self‐assembly. This is demonstrated preparation of [1+1], [2+2], [2+3] macrocyclic cage‐type structures combination with organic dicarboxylates. The linkage binders option varying number reactive M−X sites generate versatile enabling molecular tectonics instead node‐based strategy generally employed metallo‐supramolecular
Ligands derived from 2,x- and 3,y-pyridinedicarboxylic acid (x = 3–6; y 4–5) are widely used building blocks for the formation of metal-coordination polymers (MCPs), as they show a large variety bridging modes angles. Metal complexation occurs either only with carboxylate groups or through N,O-chelate ring formation. In this contribution, supramolecular chemistry solvatomorphism diorganotin complexes 2,5-pyridinedicarboxylate (25pdc) formed in presence series coordinating noncoordinating...
Four dinuclear organotin halides of composition XnPh(3–n)SnCH2Si(Me)2–C12H8–Si(Me)2CH2SnPh(3–n)Xn (X = Cl, I; n 1, 2) were prepared and combined in 1:1 stoichiometric reactions with potassium 2,5-pyridinedicarboxylate, 3,5-pyridinedicarboxylate, piperazine bis-dithiocarbamate, respectively. The yielded a total five [1 + 1] aggregates either 21- or 22-membered macrocyclic structures that fully characterized by elemental analysis, mass spectrometry, IR NMR (1H, 13C, 29Si, 119Sn) spectroscopy,...
Cocrystallizations of diboronic acids [1,3-benzenediboronic acid (1,3-bdba), 1,4-benzenediboronic (1,4-bdba) and 4,4'-biphenyldiboronic (4,4'-bphdba)] bipyridines [1,2-bis(4-pyridyl)ethylene (bpe) 1,2-bis(4-pyridyl)ethane (bpeta)] generated the hydrogen-bonded 1 : 2 cocrystals [(1,4-bdba)(bpe)2 ] (1), [(1,4-bdba)(bpeta)2 (2), [(1,3-bdba)(bpe)2 (H2 O)2 (3) [(1,3-bdba)(bpeta)2 O)] (4), wherein 1,3-bdba involved hydrated assemblies. The linear extended 4,4'-bphdba exhibited formation...

The chemical shifts of protons depend not only on the properties solute molecule but also medium in which resides. A series β-lactams with various substitution patterns were synthesized to study aromatic-solvent-induced (ASISs) chloroform and benzene by using 1H NMR spectroscopy. results agreed those obtained theoretical density functional theory calculations. β-lactam ring are most affected ASIS effect, they tend overlap due anisotropic effect benzene.
Abstract Crystalline framework materials have gained interest because of their many potential applications. A novel chiral tetrandrine salt (DNT) has been synthesized and characterized by conventional analytical techniques single‐crystal X‐ray diffraction analysis, its self‐assembly behavior studied. In the solid state, 48 molecules compound self‐assemble into an organic based on nanospherical aggregates formed exclusively through weak noncovalent interactions. Additionally, it was...
Three-dimensional hydrogen-bonded frameworks (3D HBFs) based on organotin macrocycles were obtained by self-assembly of 2,5-pyridinedicarboxylic acid and di-n-dibutyltin(IV) oxide in alcohol-chloroform mixtures subsequently stabilized substituting monoalcohol molecules within the network diols (1,4-butanediol 1,5-pentanediol). The C–C bond linkages converted solvate into struts, stabilizing noncovalent providing air-stable HBFs with large spherical hydrophobic cavities. Inclusion Nile Red...

Boroxine- and borazine-cage analogs to C20, C60, C70 were calculated compared in terms of structure, strain indicators, physical properties relevant nanoscale applications. The results show C60 type cages are less strained than the smaller congener, primarily due minimized bending B-arylene-B segments. smallest cage has a diameter 2.4 nm, which increases up 4.9 nm by either variation polyhedron (C20 < C70-type cage) or organic spacer elongation between boron centers. All porous (apertures...
