Over the past few years, the powder charge-flipping algorithm has proved to be a useful one for structure solution from powder diffraction data, so a semi-systematic study of the effect of the different input parameters on its success has been perfor

The crystal structure of NaY was re-determined in space group Fd-3m from 87 unique electron diffraction amplitudes obtained at 1250 kV by A. Carlsson, et al. (Chem. Eur. J. 5 (1999) 244), where a = 24.7 Å. The determination, based on maximum entropy

A method previously described for comparing whole crystal structures based on the correlation of fingerprint plots derived from Hirshfeld surfaces coupled with cluster analysis (A. Parkin, G. Barr, W. Dong, C. J. Gilmore, D. Jayatilaka, J. J. McKinno

Intermolecular interactions between 2-amino-4-methylpyrimidine and 2-methylbenzoic acid in the crystalline solid state, used in a recent blind test of crystal structure prediction, are classified using cluster analysis and multivariate statistics. Th

In high-throughput crystallography it is possible to accumulate large numbers of powder diffraction patterns on a series of related compounds, often polymorphs, salts or co-crystals. In previous papers [Gilmore, Barr & Paisley (2004).J. Appl. Cryst.3

ITQ-26 was synthesized via the fluoride procedure using 1,3-bis-(triethylphosphoniummethyl)-benzene as the structure-directing agent. The unit cell and space group were initially determined from electron diffraction experiments on individual tilted m

The maximum-entropy and likelihood method for solving zeolite crystal structures from electron diffraction data is modified to use potential-map-density histograms as an additional figure of merit. The experimental histogram is compared to an idealiz

Automated cluster analysis is used to examine the conformation and configuration of pyranose sugars. Previous findings on this issue are confirmed, importantly from an analysis that requires no prior knowledge of the significant factors determining t
