Fe（Pyac）_3 [PyacH=3-（4-吡啶基）-2，4-戊二酮]与AgNO_3的溶液反应生成两种类型的多孔混合金属有机骨架（M 'MOFs）。在较低的AgNO 3浓度下，产物（M 'MOF 1）具有Ag：Fe=1：1的二维蜂窝结构，孔约为1.5 μ m。12x16 A.然而，当使用较高浓度的AgNO 3时，产物（M 'MOF 2）具有Ag：Fe=3：2和多孔的一维梯形结构。各种非极性溶剂在M 'MOF 2中充当客体：与1，2-C6 H4 Cl 2，[AgNO 3]3[Fe（Pyac）3]2（1，2-C6 H4 Cl 2）5.5（M' MOF 2a）;与C6 H5 Br，[AgNO 3]3[Fe（Pyac）3]2（C6 H5 Br）6（M 'MOF 2b）。M’MOFs 2a和2b可以通过用合适的溶剂处理而在单晶到单晶的转化中相互转化。
The reaction of solutions of Fe(Pyac)3 [PyacH=3-(4-pyridyl)-2,4-pentanedione] and AgNO3 produces two types of porous mixed-metal-organic frameworks (M'MOFs). With lower AgNO3 concentrations, the product (M'MOF1) has a 2D honeycomb structure with Ag:Fe=1:1 and pores of ca. 12x16 A. When a higher concentration of AgNO3 is employed, however, the product (M'MOF2) has Ag:Fe=3:2 and a porous 1D ladder structure. A variety of nonpolar solvents serve as guests in M'MOF2: with 1,2-C6H4Cl2, [AgNO3]3[Fe(Pyac)3]2(1,2-C6H4Cl2)5.5 (M'MOF2a); with C6H5Br, [AgNO3]3[Fe(Pyac)3]2(C6H5Br)6 (M'MOF2b). M'MOFs 2a and 2b can be interconverted by treatment with the appropriate solvent, in single-crystal-to-single-crystal transformations.
