In situ hydrolysis of 4-cyanopyridine in hydrothermal synthesis of a 3-D coordination polymer, {Pb(II)(C6H4O2N)2}n

A novel luminescent Pb(II) coordination framework, {Pb(II)(C6H4O2N)2}n, have been prepared in situ hydrolysis of 4-cyanopyridine under hydrothermal condition and characterized by the elemental analyses, IR spectra, TG and single crystal X-ray diffraction. The compound presents the first framework compound constructed from isonicotinic acids and lead(II) ions, showing three-dimensional architecture with (4, 4) net self-penetrating (48 67) topology.
