A novel pillared double-layered Pb(II) coordination polymer based on 1,3,5-benzenetricarboxylic acid and dipyrido[3,2-a:2′,3′-c]-phenazine-2-carboxylic acid

A fascinating pillared double-layered three-dimensional lead(II) coordination polymer [Pb-2(BTC)(DPPZC)](n)center dot 2nH(2)O (1) has been prepared through hydrothermal reaction of lead(II) nitrate with the mixed ligands 1.3,5-benzenetricarboxylic acid (H3BTC) and dipyrido[3,2-a:2',3'-c]-phenazine-2-carboxylic acid (HDPPZC). The photoluminescent property and thermal stability oft were also investigated. (C) 2011 Elsevier B.V. All rights reserved.
