    Why negatively charged ions of d block elements never combine with ligands to form complexes? (according to one MC in past paper)

    TMs do not form negative ions ...

    Why?
    They are metals

    Cobalt and Copper form negative complexes when they go under ligand subsitution with chloride ions. [Co(Cl)4]2- and
    [Cu(Cl)4]2-

    Ligands form dative covalent bonds to TM ions. Why would a lone pair on (for example) a water molecule be attracted to a negative ion? Surely repulsion would occur?

    The OP is not asking about negative complexes, he is asking about ligands being attached to negative transition metal ions (which do not exist, because the TMs are metals)
