New benzo[f]quinolino[3,4-b][1,7]naphthyridine-6,8(5H,9H)-diones: synthesis, electronic, molecular, and crystal structures. Protonation and complexation with lanthanum and europium salts

A series of novel benzo[f]quinolino[3,4-b][1,7]naphthyridine-6,8(5H,9H)-diones, which are promising ligands for the extractive separation of actinides and lanthanides, and also their complexes with lanthanum and europium were synthesized. The molecular and crystal structures of one among the ligands were determined by single crystal X-ray diffraction. The protonation of compounds was investigated by IR and NMR spectroscopy. The electronic structure of starting substances and protonated forms was estimated by DFT calculations.
