Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
Powdery crystals of p-tert-butylthiacalixarene (2) selectively include EtOH from 1:1 mixtures of MeOH–EtOH and EtOH–PrOH, and EtCO2H from HCO2H–EtCO2H. On the other hand, no acid is included from HCO2H–MeCO2H, even though MeCO2H is included from the neat acid. The origins of these phenomena are discussed based on X-ray analysis of inclusion crystals prepared separately by crystallization.
