WebWe also undertook the conformational analysis of the detectable or purely isolated cis pentacyclic products. In 8f–i/C1 diagnostic NOE could be detected between protons H-14b and H-6. Conformation C1 was identified by further comparative DFT studies carried out on representative model diastereomers 8f/C1 and 8f/C2.

We usually think of diastereomers as optical isomers that are not mirror images of each … WebDiastereoisomers (or diastereomers) are stereoisomers not related as mirror images. (IUPAC Gold Book) Therefore cis- and trans-$\ce{[PtCl2(NH3)2]}$ are diastereomers. (E)- and (Z)-alkenes are also diastereomers of each other. Your "cis/trans stereomer" is in fact simply a subset of diastereomerism.

Web5.11 E and Z Designations for Alkenes / Introduction • For molecules with different groups attached to the C=C double bond, the E / Z notation is used instead of cis / trans notation Cis / trans isn’t adequate to differentiate between these two diastereomers • cis and trans only works if there is a like group on each carbon of the alkene Enantiomers, Diastereomers, Constitutional isomers, Same or no relationship?
