Abstract
The invention provides as new compounds cis-xis-cis-tetrasubstituted cyclopentane compounds which are expected to be useful as chelating agents for alkaline earths, transition, lanthanide, and actinide metal ions. The compounds have Formula (I). Each of the groups X.sup.1, X.sup.2, X.sup.3, and X.sup.4 comprises at least one potential ligand donor group, or one of the groups X or Z may comprise a group which may permit attachment to a biological active molecule or insoluble support. ##STR1##
