Synthesis and Structure of New Cd−Bi−S Homologous Series: A Study in Intergrowth and the Control of Twinning Patterns
Four compounds, CdBi2S4, CdBi4S7, Cd2.8Bi8.1S15, and Cd2Bi6S11, have been synthesized using a RbCl/LiCl flux. Single-crystal X-ray structure refinements were made for CdBi2S4 and Cd2.8Bi8.1S15. The…

This paper shows that at certain ideal projected cluster sizes related to one another by the golden mean (tau=(1+ radical 5)/2), constructive interference leading to tenfold diffraction patterns is optimized.
Bcc and Fcc transition metals and alloys: a central role for the Jahn-Teller effect in explaining their ideal and distorted structures.
A tight-binding function, DeltaE(star), a function that measures the energetic effects of transferring electrons within wave vector stars is developed, which allows one to connect distortions in solids to the Jahn-Teller effect in molecules and to provide an orbital perspective on structure determining deformations in alloys.

The anhydrous forms of these complexes were found to be effective catalyst precursors for the homopolymerization of propylene oxide and carbon dioxide to produce poly(propylene oxide-co-propylenecarbonate) with no propylene carbonate byproduct.
γ1-Pt5Zn21—a reappraisal of a γ-brass type complex alloy phase
Interpenetrating polar and nonpolar sublattices in intermetallics: the NaCd(2) structure.
This electronic Aufbau begins with the relatively simple Mg(17)Al(12) structure and works up to Samson's NaCd(2) structure, using quantum-mechanical calculations as a guide to describing and understanding these structures.
Pd(0.213)Cd(0.787) and Pd(0.235)Cd(0.765) structures: their long c axis and composite crystals, chemical twinning, and atomic site preferences.

Results indicate that Cd:Pd stoichiometry plays a role in phase stability.
Four-dimensional space groups for pedestrians: composite structures.
The principle of complementarity is developed, which allows one to identify correctly 4D space groups solely from examination of the two 3D components that make up a typical 4D composite structure.
