A novel lead(II) framework containing Pb–O–Pb and Pb–Cl–Pb helical chains
چکیده انگلیسی

Under hydrothermal conditions, using 5-methyl-pyrazine-2-carboxylic acid (HL) and lead(II) chloride, a new 2D lead(II) framework [Pb(L)(μ2-Cl)(H2O)]n can be isolated, in which infinite Pb–O–Pb helical chains can be observed. Interestingly 1 stacks in ABAB… ways, in one layer right-handed Pb–O–Pb and left-handed Pb–Cl–Pb helical chains are inter-connected while the opposite chiral Pb–O–Pb and Pb–Cl–Pb helical chains are included in the neighboring layer. Solid state luminescent spectrum of 1 also has been investigated indicating strong emission bands centered at 452 nm.
