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. In the experiment, the researchers used many compounds, for example, Phenyl(pyridin-2-yl)methanone (cas: 91-02-1Safety of Phenyl(pyridin-2-yl)methanone).
Phenyl(pyridin-2-yl)methanone (cas: 91-02-1) belongs to pyridine derivatives. Pyridine’s the lone pair does not contribute to the aromatic system but importantly influences the chemical properties of pyridine, as it easily supports bond formation via an electrophilic attack. Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.Safety of Phenyl(pyridin-2-yl)methanone
