以CuSO_4·5 H_2 O、三吡啶三嗪（tpytrz）、MoO_3和H_2 O为原料，在160°C下水热反应84 h，得到绿色针状[Cu（tpytrz）_2Mo_4 O_（13）]（MOXI-37）。MOXI-37的结构由占据层间区域的tpytrz配体支撑的双{CuMo_4 O_（13）}层组成。整体结构采用了许多有机-无机复合材料所特有的无机和有机亚基交替的主题。无机网络由角共享八面体和四面体的{Mo 4 O 13}链构成，通过八面体{CuN 2 O}单元连接成二维结构。MOXI-37的结构可以与包含桥接有机氮配体的铜-钼网络的其他实例，即[Cu（dpe）MoO 4]（MOXI-1）和[Cu（bpa）0.5MoO4]（MOXI-24）进行比较。与MOXI-37的网络连接性不同，[Cu（dpe）MoO 4]的层状结构由共角{MoO 4}四面体和{CuN 2 O 5}三角双锥组成，而二维氧化物亚结构[Cu（bpa）0.5MoO4]由通过共角{MoO 4}四面体连接的四核铜簇构成.
Abstract The hydrothermal reaction of CuSO4·5H2O, tripyridyltriazine (tpytrz), MoO3, and H2O in the mole ratio 2.1:1.0:1.9:3470 for 84 h at 160°C yields green needles of [Cu(tpytrz)2Mo4O13] (MOXI-37). The structure of MOXI-37 consists of bimetallic {CuMo4O13} layers buttressed by tpytrz ligands occupying the interlamellar region. The overall structure adopts the motif of alternating inorganic and organic subunits characteristic of many organic–inorganic composite materials. The inorganic network is constructed from {Mo4O13} chains of corner-sharing octahedra and tetrahedra, linked by octahedral {CuN2O} units into a two-dimensional structure. The structure of MOXI-37 may be compared to other examples of copper–molybdate networks sandwiching bridging organonitrogen ligands, namely, [Cu(dpe)MoO4] (MOXI-1) and [Cu(bpa)0.5MoO4] (MOXI-24). In contrast to the network connectivity of MOXI-37, the layer structure of [Cu(dpe)MoO4] consists of corner-sharing {MoO4} tetrahedra and {CuN2O5} trigonal bipyramids, while the two-dimensional oxide substructure [Cu(bpa)0.5MoO4] is constructed from tetranuclear copper clusters linked through corner-sharing {MoO4} tetrahedra.
