Abstract

The crystal structures of 1,4-bis(3,5-di-tert-butyl-2-hydroxybenzamido) butane (1) and 1,3-bis(3,5-di-tert-butyl-2-hydroxybenzamido)-2,2-dimethylpropane (2) have being characterized by single crystal X-ray diffraction. Their crystal packing is discussed in terms of the different interactions they exhibit. A brief discussion, based on hydrogen bonds, on the structural features of bis-(3,5-di-tert-butyl-2-hydroxybenzamide) compounds is carried out. © The Royal Society of Chemistry 2007.
