The results of the study of the chiroptical properties (CD, ORD and [α]), of fourteen optically active monosubstituted cymantrene derivatives with a chiral center directly attached to the Cp ring are summarized for the first time. It has been found that the (R)-enantiomers of these compounds exhibit a negative Cotton effect for the “metallocenyl” transition in CD spectra within the range 310–360 nm
