The use of platinum complexes ((Pt(2)(P(2)O(5)H(2))(4))4- and selected model rhodium(III) compounds in the development of single crystal monochromatic excited-state crystallography

Excited-state crystallography is a new and exciting technique that is revolutionizing crystallography. Chapter one discusses the work done by other groups on excited-state crystallography. The second chapter introduces previous work done on ruthenium nitrosyls. In order to develop this new method model compounds are needed that diffract well. A select few Rh(III) compounds have been synthesized and investigated through the use of density functional theory calculations. The instrumentation and technique that have been developed and implemented are also discussed. The first results of monochromatic single crystal excited-state crystallography on [Pt₂(P₂O ₅H₂)₄]4− are presented and reviewed.
