The salt diaquo-diammine-bis(3,4'-bi-1,2,4-triazolate) copper(II) of the formula [Cu(bTA-)2(NH3)2(H2O)2] has been synthesized and structurally characterized by X-ray single crystal diffraction analysis. This complex adopts a monomeric structure. This monomer crystallizes in the triclinic system, space group P1 with a=5.9657 Å; b=6.8975 Å; c=9.9892 Å; α=106.181°; β=97.868°; γ=90.800° and Z=1. The Cu atom is coordinated by two nitrogen atoms of two monodentate bitriazolate ligands, two nitrogen atoms of NH3 and two water molecules in a distorted octahedral geometry. The complex has been also characterized by elemental analysis and studied by electronic and vibrational spectroscopy. The obtained results are in good agreement with the structure determined by X-ray diffraction analysis.

Introducing and stabilizing oxygen vacancies in oxide catalysts is considered to be a promising strategy for improving catalytic activity and durability. Herein, we quantitatively create oxygen vacancies in the lattice of porous single-crystalline β-GaO monoliths by reduction treatments and stabilize them through the long-range ordering of crystal lattice to enhance catalytic activity and durability. The combination analysis of time-of-flight neutron powder diffraction and extended x-ray absorption fine structure discloses that the preferential generation of oxygen vacancy tends to occur at the site of tetrahedral coordination oxygen ions (O sites), which contributes to the formation of unsaturated Ga-O coordination in the monoclinic phase.

A bioassay-guided chemical investigation of the endophytic fungus F5 resulted in the discovery of two novel sesquiterpenes, chamilactones A and B ( and ), with a new 9,10-seco-15--isoilludalane carbon skeleton, together with several biosynthetically related precursors (-). Their structures and absolute configurations were elucidated by the analysis of MS, NMR, calculated C chemical shifts, ECD calculations, and single-crystal X-ray diffraction data. It was proposed that an unprecedented carbon-carbon bond cleavage between C-9 and C-10 in - was the key step in the biosynthetic pathway of and .

Next-generation real-time gas sensors are crucial for detecting multiple gases simultaneously with high sensitivity and selectivity. In this study, ternary metal sulfide (PbSnS)-incorporated metal oxide (SnO) heterostructures were synthesized via a one-step hydrothermal method. Characterizations such as X-ray diffraction, high-resolution transmission electron microscopy, and X-ray photoelectron spectroscopy confirmed the successful formation of PbSnS/SnO heterostructures.
