A group of functionalized amine chelants having ortho ligating functionality that form complexes with rare-earth type metal ions are disclosed. The chelants possess the general formula ##STR1## wherein R.sup.'1, R.sup.'2, R.sup.'3, R.sup.'4, R.sup.'5 and R.sup.'6, Z' and X are all defined in the specification. In addition certain of the chelant-radionuclide complexes can be effectively employed in compositions useful as therapeutic and/or diagnostic agents for calcific tumors and/or relief of bone pain.
