In the title complex, [CuCl(C(14)H(12)N(4))(2)], the Cu(I) atom, lying on a twofold rotation axis, is coordinated by two N atoms of two 1,2,3,4-tetra-hydro-1,4,6,11-tetra-aza-naphthacene ligands and one Cl atom, also lying on the twofold rotation axis, in a distorted trigonal-planar geometry. The complex mol-ecules are connected into a one-dimensional structure along [001] via N-H⋯N hydrogen bonds and further into a three-dimensional structure via N-H⋯Cl hydrogen bonds. π-π inter-actions between the pyrazine and benzene rings and between the benzene rings [centroid-centroid distances = 3.5635 (15) and 3.9128 (16) Å] are present.

Nitrenes (R-N) have been subject to a large body of experimental and theoretical studies. The fundamental reactivity of this important class of transient intermediates has been attributed to their electronic structures, particularly the accessibility of triplet vs singlet states. In contrast, electronic structure trends along the heavier pnictinidene analogues (R-Pn; Pn = P-Bi) are much less systematically explored.

Context: Hydrogen storage in porous nanostructured compounds have recently attracted a lot of attention due to the fact that the underlying adsorption mechanism and thermodynamics provide suitable platform for room temperature adsorption and desorption of H molecules. This work reports the findings of a study on the reversible hydrogen storage capacities of Sc and Y decorated C fullerene, conducted using dispersion-corrected density functional theory (DFT) calculation. The transition metal (TM) atoms, such as Sc and Y, are identified to attach to the C-C bridge position of the C fullerene through non-covalent closed-shell interactions.

In the title salt, CHN ·HPO , the complete dication is generated by a crystallographic centre of symmetry with the methyl groups in equatorial orientations. The complete dianion is generated by a crystallographic twofold axis with the central O atom lying on the axis: the P-O-P bond angle is 135.50 (12)°.

KRAS (Kirsten rat sarcoma viral oncogene homologue), the most common mutated protein in human cancers, is the leading cause of morbidity and mortality. Before Sotorasib (AMG-510) was approved for non-small cell lung cancer treatment in 2020, the oncogenic KRAS mutations were believed to be non-druggable. High-resolution X-ray crystal structures of GDP-bound KRAS mutants with and without inhibitor are resolved and deposited in the Protein Data Bank (PDB).

The S state relaxation dynamics of chlorobenzene (CB), 3-chlorophenol (3-CP), 3-CP·HO, and 2-chlorophenol·HO (2-CP·HO) have been investigated by means of picosecond time-resolved pump-probe spectroscopy in a state-specific manner. For CB, the S state relaxes via the S-S internal conversion in the low internal energy region (<2000 cm), whereas the direct C-Cl bond dissociation channel mediated by the upper-lying repulsive πσ* state is opened to give the rather sharp increase of the S relaxation rate in the high internal energy region (>2000 cm). A similar dynamic feature has been observed for 3-CP in terms of the lifetime behavior with an increase in the S internal energy, suggesting that the H atom tunneling dissociation reaction from OH might contribute less compared to the internal conversion, although it is not clear at the present time whether or not the sharp increase of the S relaxation rate in the high internal energy region of 3-CP (>1500 cm) is entirely due to that of the internal conversion.
