    “…Treatment of HOAr(P) with Ln(III)[N(SiMe(3))(2)](3) (Ln = La, Sm, Y, Yb) in a 3:1 molar ratio yielded the mononuclear rare-earth metal complexes Ln(III)(OAr(P)-κ(2)O,P)(3) (2-Ln). The heterobimetallic rare-earth metal–silver complexes Ln(III)(OTf)(μ-OAr(P)-1κ(1)O,2κ(1)P)(3)Ag(I) (3-Ln) were prepared from monometallic precursors by reactions of equimolar amounts of 1 with Ln(III)[N(SiMe(3))(2)](3) or 2-Ln with silver(I) triflate, respectively. …”

    “…In clinical practice, evaluation of clinical efficacy of treatment planning stems from the radiation oncologist's experience in accurately targeting tumors, while keeping minimal toxicity to various organs at risk (OAR) involved. A more objective, quantitative method may be raised by using radiobiological models. …”
