There are two types of structural isomers (also called constitutional isomers): coordination isomers (also called ionization isomers), which produce different complex ions in solution, and linkage isomers, which differ in the metal-to-ligand linkage. the former can be viewed as containing different complex salt ions. from the following pairs of coordination complexes, identify the one that is a pair of coordination isomers (aka ionization isomers).na2[nibr2cl2] and k2[nibr2cl2][ni(nh3)3br]cl and [ni(nh3)3cl]br[ni(nh3)3(h2o)]so4 and [ni(nh3)2(h2o)2]so4which of the following pairs of coordination complexes are linkage isomers? a.
