Congratulations to Karim Sutton, who has been awarded a Margaret C. Etter Student Lecturer Award at the recent American Crystallographic Association annual meeting in Boston.
He presented his recent research determining oxidation states in mixed-valent materials using tunable synchrotron radiation on Diamond beamline I19.
The awards were established to honour the memory of Professor … Read the rest
The results have just been announced for the latest round of applications to the John Fell Oxford University Research Fund. Our application for funding for meetings for the Red Kite network over the next three years was successful, which is excellent news and should secure its immediate future.… Read the rest

Pyridinium-3,5-bis(triazole) can bind anions through polarised C-H···anion hydrogen bonds. We have incorporated this motif into pseudorotaxanes, catenanes and rotaxanes (in conjunction with an isophthalamide macrocycle), and the resulting interlocked architectures are formed in high yields and display interesting and unusual anion … Read the rest

Leverages measure the influence that observations (intensity data and restraints) have on the fit obtained in crystal structure refinement. Further analysis enables the influence that observations have on specific parameters to be measured. The results of leverage analyses are discussed in the context of the … Read the rest

Tetraisohexylammonium bromide [systematic name: tetrakis(4-methylpentyl)azanium bromide], C24H52N+·Br–, is a powerful structure II clathrate hydrate crystal-growth inhibitor. The crystal structure, in the space group P3221, contains one ammonium cation and one bromide anion in the asymmetric unit, … Read the rest

Uranium complexes of bis(p-tert-butyl-salicylidene)-1,2-diphenylethylenediamine (1) and bis(salicylidene)-1,2-diphenylethylenediamine (2) have been synthesized and investigated by X-ray single crystal diffraction and MD calculations in Periodic Boundary Conditions. Both compounds form crystals which are densely packed and do not provide voids accessible to … Read the rest
