In the title compound, [Cu(CHNO)(CHN)(HO)]·2HO, the Cu atom is coordinated by three O atoms and two N atoms, provided by a tridentate pyridine-2,6-di-carboxyl-ate (pdc), one pyrazole and one water ligand, forming a slightly distorted square-pyramidal geometry [range of O-Cu-O and O-Cu-N bond angles = 79.55 (8)-166.22 (10)°]. The water mol-ecule is positioned at the apical position. In the crystal, the complex mol-ecule and the two crystallographically independent non-coordinating water mol-ecules are linked into a supra-molecular layer structure parallel to the plane O-H⋯O and N-H⋯O hydrogen bonds.

Hydrous aluminosilicates are important deep water-carriers in sediments subducting into the deep mantle. To date, it remains enigmatic how hydrous aluminosilicates withstand extremely high temperatures in the mantle transition zone. Here we systematically investigate the crystal structures and chemical compositions of typical hydrous aluminosilicates using single-crystal X-ray diffraction, electron probe microanalyzer, and nanoscale secondary ion mass spectrometry.

The application of chitosan in packaging has always been limited due to its brittle and hygroscopic nature. In this study, hydrophobic short-chain fatty acids (SCFAs) were utilized to modify chitosan to overcome this issue. For the first time, hydrophobic SCFAs, typically hexanoic acid and its homologs, were found to be able to dissolve chitosan in water as well as its hydrophilic analog.

Thio/selenoimidazole Nπ-methyltransferases are an emerging family of enzymes catalyzing the final step in the production of the S/Se-containing histidine-derived antioxidants ovothiol and ovoselenol. These enzymes, prevalent in prokaryotes, show minimal sequence similarity to other methyltransferases, and the structural determinants of their reactivities remain poorly understood. Herein, we report ligand-bound crystal structures of OvsM from the ovoselenol pathway as well as a member of a previously unknown clade of standalone ovothiol-biosynthetic Nπ-methyltransferases, which we have designated OvoM.
