Transitional elements

  1. Jun 26, 2007 #1
    Can any body please tell me why NH3 readily forms complex ions with transitional elements but NH4+ doesn't?

    Complexes of this type are generally between electron donors (ligands) and electron acceptors (empty d shell orbitals in transition metals).

    this is what I think ; NH3 has 2 unpaired electrons and they can bond with the d orbitals of tranisitional metals. However, NH4+ doesn't have an unpaired electron and can only substitute its H.

    Am I on the right track?
