Abstract

The crystal preparation and structure of a cyclic derivative of γ-amino­butyric acid, GABA, is reported.

Bis(benzoxazol-2-yl)methanides in main group organometallic syntheses and enquiry-based education

“…[51] Since its introduction, the MetalJet X-ray source has been used in single crystal X-ray diffraction studies involving all kinds of different compounds. From small organic molecules [59][60][61][62][63][64] to proteins, [65][66][67][68] polymers [69,70] and metal organic frameworks. [71] Furthermore inorganic compounds containing p-block elements [72,73] as well as d-metal complexes [74][75][76][77][78][79][80] have been investigated.…”

“…A set of objects prepared in this way and a laboratory stand at hand, in principle all types of screw axes can be modelled, if the correct number of ducks is arranged in a suitable manner. With certain screw axes (42,62,63,64) two or more objects occupy positions at the same height. To be able to accurately model this, special mounts were designed, which have several pieces of sheet metal attached to the same aluminium block (see Figure 2 -18).…”
