Synthesis, structures and characters of one 3D 2-fold interpenetrating net with rare 42638 topology

Herein, one metallic–organic coordinated polymer, namely Cd2(bpp)3(μ2-Cl)2(μ-Cl)2 (1) (bpp = 1,3-bis(4-pyridyl)propane) was synthesized hydrothermally by the reaction of bpp ligands with CdCl2, possessing the 3D 2-fold interpenetrating nets with the rare four-connected sra-type zeolite topology. Further, the luminescent and thermal stability characters are investigated, and the results reveal that they could to be potential, microporous and fluorescent materials.
