15. Although all copper corrole structures exhibit saddling, the fact that copper corroles are inherently saddled was first pointed out in: Alemayehu A, Gonzalez E, Hansen LK and Ghosh A. Inorg. Chem. 2009; 48: 7794-7799. By 'inherently', we mean that the saddling is due primarily to metalligand orbital interactions and is observed even in the absence of sterically hindered substituents.
16. Saddling was noted for a sterically hindered copper corrole by Bröring et al.: Bröring M, Brégier F, Tejero EC, Hell C and Holthausen MC. Angew. Chem. Int. Ed. Engl. 2007; 46: 445-448.
