Abstract
Group 3 and rare-earth triflate-complexes M(OTf)2(bdmpza) {M = Sc (1Sc), Y (1Y), La (1La), Sm (1Sm), Eu (1Eu) OTf = SO3CF3} bearing the heteroscorpionate bdmpza ligand {bdmpza = bis(3,5- dimethyl-pyrazol-1-yl)acetate} have been synthesized and characterized, together with the yttrium and europium complexes M(OTf)(bdmpza)2 {M = Y (2Y), Eu (2Eu)}. The coordination mode of the [N,N,O]-donor ligand in these complexes has been elucidated by means of DFT calculations. The cytotoxic effect of selected complexes and of the free ligand towards HeLa cells has been evaluated.File in questo prodotto:
