| 摘 要： | A new 3D Pb(Ⅱ) coordination polymer Pb2(L)2(dea)]n·nH2O has been hydrothermally prepared by using the long flexible decanedioic acid (H2dea) and the N-donor chelating ligand 2-(1H-l,3,7,8-tetraazacyclopental]phenanthren-2-yl)naphthol (HL). Single-crystal X-ray determi- nation shows that the complex crystallizes in the monoclinic system, space group C2/c with a = 25.453(5), b = 7.5035(15), c = 27.340(6),β= 114.84(3)°, V = 4738.6(16)3, Z = 8, C28H22N4O4Pb, Mr = 685.69, Dc = 1.922 g/cm3, F(000) = 2656, μ(MoKa) = 7.166 mm-1, R = 0.0282 and wR = 0.0687. Two L ligands bridge two Pb(Ⅱ) atoms to form a dimmer, and the neighboring dimers are further linked by the dea ligands to yield a 3D structure. The IR and TG of the compound have been investigated in detail.
