At the University of Illinois, he developed an active research program on coordination chemistry. He is referred to as the “Father of Coordination Chemistry in the United States,” as prior to his time, this area of chemistry received little attention in the U.S. The Bailar twist in coordination compounds is named after him. He helped found the book series Inorganic Syntheses and the journal Inorganic Chemistry. His work was widely recognized culminating in the award of the Priestley Medal from the American Chemical Society, an organization of which he was also president.
