Synthesis, Structure, and Luminescent Property of a Heterometallic Metal−Organic Framework Constructed from Rod-Shaped Secondary Building Blocks

A new heterometallic MOF compound, [ZnNa(m-BDC)2]·NH2(CH3)2 (MOF-CJ2), has been solvothermally synthesized
and characterized by single-crystal X-ray diffraction, X-ray powder diffraction, ICP, TGA, IR, and photoluminescence
spectroscopy analyses. It crystallizes in monoclinic space group C2/c (No. 15) with a = 13.277(6) Å, b = 14.323(7) Å, c = 11.328(6) Å, and β = 111.73(2)°. Its framework is constructed from M−O−C (M = Na and Zn) rods
composed of alternating six-coordinated Na(I) centers and four-coordinated Zn(II) centers. These rods are linked
by m-BDC links to form primitive cubic (pcu) type rod packing. This framework exemplifies the first open-framework
heterometallic MOF structure based on the assembly of infinite rod building units.
