forms of
adipic acid are

dianionic monodentate (M=S), or

- the lone pair on bi****h is
unexpectedly stereochemically inactive. The
dianionic complex [BiCl5]2− does
however adopt the
expected square pyramidal structure...

attached to the "axial sites" of the iron. The
porphyrin ring is a
planar dianionic,
tetradentate ligand. The iron is
typically Fe2+ or Fe3+. One or two ligands...

Being dianionic,
tetrachlorozincate is not
classified as a
weakly coordinating anion. On the
other hand,
being dianionic, tetrachlorozincate...

actinide series. They

sandwich structure with two
dianionic cyclooctatetraenyl ligands (COT2-,

- Both
porphyrins and
