The synthesis, characterization, and computational analysis of a series of low-valent, In(I) complexes bearing the bis(imino)pyridine scaffold, Ar′N═CPh}2(NC5H3), is reported. A stepwise steric reduction of the aryl groups on the imine substituents around the coordination site, (Ar′ = 2,5-tBu2C6H3, 2,6-iPr2C6H3, 2,6-(CH3CH2)2C6H3) is explored through the spectroscopic and crystallographic examination
