A New 3D Pb(II) Inorganic–Organic Hybrid Framework Based on Terephthalate Acid with the Inorganic Pb–O–Pb Connectivity

Solvothermal reaction of Pb(NO 3 ) 2 with terephthalate acid afforded one new inorganic–organic hybrid framework, [Pb(PBDC)] n ( 1 ) (H 2 PBDC = terephthalic acid). X-ray analysis shows that compound 1 crystallizes in orthorhombic space group Pbca and the two carboxy group of terephthalate acid adopt rare coordination modes. A noticeable point in this paper that compound 1 exhibits preferable catalytic property on degradation of Rhodamine B. The phase purity of the as-synthesized sample was confirmed by powder X-ray diffraction. Moreover, satisfactory elemental analysis, IR spectra, and thermogravimetric analysis were obtained.
