factual connectivities between metal atom and organic group(s) since in
reality these compound types comprise predominantly oligomeric aggregates and/or solvated complexes. In a simplifying manner, however, their
names are usually formed from the fundamental monomeric structural
units by a) prefixing the name of the organic substituent group to the
unchanged name of the metal - thus following inorganic coordination
nomenclature - or b) regarding these substances as salts of organic
anions.
