When these species have ambiguous oxidation states, they are called non-innocent. M. L. H. Green’s covalent bond classification method characterizes these species as L, X, or Z, based on if they are electron acceptors or donors. These species are often illustrated as bases using hard soft acid base theory. The ability of these species to be bound at multiple sites results in (*) linkage isomerism. (10[1])The presence of these species tends to produce absorbances in the visible range due to d-orbital splitting. (10[1])When they can (10[1])bind at multiple sites, these species have higher denticity, which may (10[1])allow for chelation. (10[1])For 10 points, name these species that bind metal atoms in coordination (10[1])complexes. ■END■ (0[4])
