Oliveira Araujo, Vinicius published the artcileLead(II) compounds with neutral coordination of semicarbazones: Synthesis and characterization, Related Products of pyridine-derivatives, the publication is Inorganica Chimica Acta (2022), 120785, database is CAplus.
2-Benzoylpyridine semicarbazide/4-phenylsemicarbazide derived ligands as hydrochloride salts, [H2L]Cl and [H2LPh]Cl·2H2O, react with Pb2+ ions in aqueous and organic milieus. The compounds [Pb2(HL)2Cl4]·2DMF (1a), [Pb2(HL)2Cl4]·5H2O (1b), [Pb2(HL)2Cl2(NO3)2]·4H2O (2), [Pb2(HL)2(SCN)4] (3), [Pb4(HLPh)4Cl8] (4), [Pb(HLPh)2(NO3)2] (5) and [Pb(HLPh)2(SCN)2] (6) were obtained and characterized by powder x-ray diffraction and by IR and UV-visible spectroscopies. Compounds 1–5 were analyzed by single-crystal x-ray diffraction. Tetrel and hydrogen bonds dominate the solid-state arrangements. The aqueous synthetic approach makes the pre-ligands of this work promising for further studies in aqueous coordination chem. with p-block metal ions. [H2L]Cl and [H2LPh]Cl·2H2O are suitable for coordination as neutral HL or HLPh species.
