The splitting of the ν(I-Cl) and ν(C=O) bands of ICl complexes with carbonyl bases in highly diluted heptane solutions is explained by the existence of two 1:1 stereoisomeric complexes: a linear complex (ICl along the axis of the carbonyl bond) and an angular complex (ICl in the direction of a lone pair).In the series RCOOEt, RCOPh, RCOt-Bu, R2CO, RCONPh2, and RCONMe2, where R = Me, Et, i-Pr, or t-Bu, the angular complex for R = Me transforms into the linear complex for R = t-Bu, since bulky substitutents on the carbonyl group destabilize the angular arrangement.In the series RCOH and RCOMe the complex is angular whatever the steric effect of R, since ICl is located on the lone pair near the small H or Me substituents.When ICl is added in excess, a 1:2 complex appears.
