A Pb(II)-Na(l) coordination polymer, ([Pb3NaL3](Me2NH2)(2)(C2H5OH)(1.5)(H2O)(10.5)}(n) (1) (H3L = 4,4',4 ''-s-triazine-2,4,6-triyl-tribenzoic acid), was synthesized under solvothermal condition. This structure crystallizes in the orthorhombic system and shows a 3D pillar-layer network. Topologically, it shows complicate (3,4,5,6,7)-connected net with Schlafli symbol of (4(2) center dot 6(8) center dot 8(9) center dot 10(2))(4(3 center dot)6(2 center dot)8)(2)(4(3)center dot 6(6)center dot 8)(2)(4(8) center dot 6(6) center dot 8)(6(3)). Luminescent investigations reveal that 1 can detect Fe3+ with relative high sensitivity and selectivity, and show broad linear range of 01000 pM, as well as low detection limits of 8.65 nM for Fe3+.
