Secondary sources should only be cited if you are unable to obtain the original.
Cite the original source as a footnote or endnote, or refer to within the text. Cite the secondary source (i.e. the article/book you read) in your References list.
For example, if you read a work by Lyon et al. (2014) in which Rabbitt (1982) was cited, and you were unable to read Rabbitt's work yourself, cite Rabbitt's work as the original source, followed by Lyon et al.'s work as the secondary source. Only Lyon et al.'s work appears in the reference list.

"Chicago requires an access date in citations of websites and other sources consulted online only if no date of publication or revision can be determined from the source. In those cases - that is, when only an access date is used- record n.d. as the date of publication in the reference list entry and for the in-text citation. To avoid conflation with the name of the author, n.d. is always lower case." (Chicago Manual of Style, 17th ed., pp. 915-916)
