Abstract
A new Pb-based coordination polymer synthesized with pyrazine-2,3-dicarboxylic acid (H2pzdc) is reported along with its structural characterizations. The compound, Pb2Cl2(Hpzdc)2(H2O)2 (1), is synthesized using a simple, aqueous-based dissolution–slow evaporation method with optimized conditions. It crystallizes in the C2/m space group (a = 11.561(1) A, b = 8.4327(7) A, c = 11.792(1) A, β = 126.3070(8)°), with a 1D coordination polymer consisting of Pb2Cl2 dimers with monoprotonated dicarboxylic acids located between the chains. Soaking 1 in an aqueous solution of Hg(II) or Co(II) at room temperature resulted in a structural transformation into a newly formed 2D or 3D structure, respectively. The 2D compound, Pb(pzdc)(H2O) (2), crystallizes in the Pbca space group (a = 9.2624(9) A, b = 12.0268(9) A, c = 13.9430(8) A), whereas the rapidly formed 3D compound, Pb2.67Co0.33(pzdc)3(H2O) (3), crystallizes in the P21/n space group (a = 10.9665(7) A, b = 8.1909(4) A, c = 25.0238(1) A, β = 91.593(5)°).
