The interesting case, however, occurs when only some of the stereocenters are inverted. Stereoisomers that differ at some stereocenters but not at others are not mirror images, so they are not enantiomers. Instead, they are diastereomers. A diastereomer is simply any stereoisomer that is not an enantiomer. Technically, cis-trans isomers are diastereomers.
