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) A, b=14.323(7) A, c=11.328(6) A, and beta=111.73(2) degrees. 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.
一种新型异金属金属有机框架化合物[ZnNa(m - BDC)₂]·NH₂(CH₃)₂（MOF - CJ2）已通过溶剂热法合成，并通过单晶X射线衍射、X射线粉末衍射、电感耦合等离子体质谱、热重分析、红外光谱和光致发光光谱分析进行了表征。它结晶于单斜空间群C2/c（编号15），a = 13.277(6) Å，b = 14.323(7) Å，c = 11.328(6) Å，β = 111.73(2)°。其骨架由由交替的六配位Na(I)中心和四配位Zn(II)中心组成的M - O - C（M = Na和Zn）棒构建而成。这些棒通过间苯二甲酸二羧酸连接形成原始立方（pcu）型棒堆积。该骨架代表了基于无限棒状构建单元组装的首个开放框架异金属金属有机框架结构。
