Syntheses and Characterizations of Zinc(II) Compounds Containing Three-Dimensional Interpenetrating Diamondoid Networks Constructed by Mixed Ligands

Three three-dimensional interpenetrating diamondoid zinc(II) compounds, [Zn(bpe)(OH-BDC)] n ( 1 ), {[Zn(dpe)(OH-BDC)](dpe) 0.5 } n ( 2 ), and {[Zn(bpp)(OH-BDC)](H 2 O)} n ( 3 ), have been prepared solvothermally by assembly of OH-H 2 BDC, Zn II with bpe, dpe, and bpp, respectively [OH-H 2 BDC = 5-hydroxyisophthalic acid, bpe = 1,2-bis(4-pyridyl)ethane, dpe = 1,2-di(4-pyridyl)ethylene, and bpp = 1,3-bi(4-pyridyl)propane]. Single-crystal X-ray diffraction analyses reveal that 1 is a 5-fold interpenetrating diamondoid network, and 2 and 3 are 4-fold interpenetrating diamondoid structures with dpe guest molecules and water molecules, respectively.
