In the symbiotic effect, a hard ligand tends to form ionic M-L bonds in which L retains more negative charge than in a soft ligand case, letting the metal ion keep more of its positive charge and hence attract additional hard ligands, […]. The antisymbiotic effect, also called transphobia, applies to pairs of high trans effect, soft ligands on a soft metal. Where a choice exists, there is a strong tendency for such ligands to avoid being mutually trans by becoming cis and preferring to have low trans effect, hard ligands trans to themselves.
