A novel 3D 2-fold interpenetrated framework assembled via mixed bridging ligands

Hydrothermal reaction of Cd(NO3)2, NaH2SIPA (5-sulfoisophthalalic acid monosodium salt) and pyrazine (Pz) resulted in a new polymeric complex {[Cd3(SIPA)2(pyrazine)(H2O)6] · 2H2O}n. X-ray structure analysis reveals that this complex features a 2-fold parallel interpenetrated 3D → 3D entanglement architecture, in which the single 3D network is constructed from {[Cd3(SIPA)2(H2O)6]}n 2D neutral layers interconnected by pyrazine ligands.

A 2-fold parallel interpenetrated 3D → 3D entanglement architecture based on the connectivity of cadmium(II) cations, the 5-sulfoisophthalate and the rigid pyrazine ligands.Figure optionsDownload as PowerPoint slide
