Abstract
A 3-D metal-organic framework (MOF) {Zn4(μ3-OH)2(bdc)3(pad)2}·2H2O (1, H2bdc = 1,4-benzenedicarboxylic acid, pad = 1,10-phenanthroline-5,6-dione) with unusual Zn4(μ3-OH)2(COO)6(N2)2 secondary building units (SBUs) has been hydrothermally synthesized and characterized by single crystal X-ray diffraction, powder X-ray diffraction, thermogravimetric analysis, elemental analysis, and infrared spectroscopy. The tetranuclear Zn4 SBU was formed through two dinuclear Zn2 clusters by sharing two μ3-OH bridges. Considering this Zn4 SBU as a six-connected node, the overall framework of 1 has a pcu topology. This tetranuclear Zn4 SBU can be used as a node in construction of MOFs.
