Structure and absolute configuration of natural fungal product beauveriolide I, isolated from Cordyceps javanica, determined by 3D electron diffraction

The crystal structure of the natural fungal product beauveriolide I, isolated from the fungus Cordyceps javanica (Bally) Kepler, B. Shrestha & Spatafora, was subjected to 3D electron diffraction experiment and its absolute structure was determined by dynamical refinement.

Crystal structure and Hirshfeld surface analysis of a salt of anti­neoplastic kinase inhibitor vandetanib

The structure of a 1:1 salt of vandetanib and bumetanide is reported. The roles of the inter­molecular inter­actions in the crystal packing were clarified using Hirshfeld surface analysis, and two-dimensional fingerprint plots indicate that the most important contributions to the crystal packing are from H⋯H, O⋯H/H⋯C, C⋯H/ H⋯C and N⋯C/C⋯N contacts.

Isostructural behaviour in ammonium and potassium salt forms of sulfonated azo dyes

Of five ammonium salt forms of sulfonated azo dyes, three are found to be isostructural with either their K or Rb congeners.

Synthesis and crystal structure of a silver(I) 6-methyl­mercaptopurine riboside com­plex

Silver has an almost linear primary coordination with two N-bound 6-methyl­mercaptopurine riboside ligands and a nitrate anion giving weaker secondary coordination in a bidentate mode.

Oxygen quenching of structurally characterized [5,10,15,20-tetra­kis­(4-fluoro-2,6-di­methyl­phen­yl)por­phy­rinato]platinum(II)

A newly synthesized and crystallographically characterized platinum por­phy­rin is efficiently quenched by oxygen as determined by steady-state and time-resolved spectroscopy.
