2 Contents: I. Experimental details of vapor adsorption experiments: Adsorption and desorption isotherms were obtained via TA Instruments Q5000 SA and VTI-SA high sensitivity thermogravimetric dynamic vapor sorption analyzers which enable sorption analysis of dry powder samples of FMOF-1 under controlled temperature and relative humidity/pressure. The balance has a signal resolution of 0.01 μg, and a sensitivity of 0.1 μg. These isotherms were measured at 25 C by monitoring the weight change of the sample as a function of relative humidity (RH) of water or relative pressure (RP) of solvents for a known weight of FMOF-1 (~10 mg). RH or RP levels were stepped up from 0% to 98% with an increment of 10% in each step and then were stepped down to 0%. Real time weight, temperature, and RH or RP were recorded. When weight change less than 0.01% for 10 min was observed, the test automatically moved to the next step of RH or RP. II. Crystallographic Details: Single crystals of FMOF-1 2Toluene were obtained by immersing a single crystal of vacuum-dried single crystal of FMOF-1 in a toluene solvent overnight. FMOF-2 4Toluene was prepared by heating vacuum-dried crystal of FMOF-1 overnight and then recrystallizing from MeCN-toluene in ~5% yield. Crystal structure determination for both compounds was carried out using a Bruker SMATR APEX2 CCD-based X-ray diffractometer equipped with a low temperature device and Mo-target X-ray tube (wavelength = Å). Measurements were taken at 100(2) K. Data collection, indexing, and initial cell refinements were carried out using APEX2, 1 whereas frame integration and final cell refinements were done using SAINT. 2 2

3 Absorption corrections were applied using the program SADABS. 3 In the solvated FMOF-1 2Toluene, the C atoms of the highly disordered toluene molecules were refined isotropically. The remaining non-hydrogen atoms in both compounds, including C atoms of toluene guest molecules in the FMOF-2 4Toluene structure, were refined anisotropically. Hydrogen atoms in the solvent molecules of the compounds were placed in idealized positions and were refined as riding atoms. Structure solution, refinement, graphic and generation of publication materials were performed by using SHELXTL software 4 while some packing diagrams were generated utilizing the Mercury software. Refinement details, structural parameters, bond lengths and angles are given in Tables S1 -S6. References 1.

SHELXTL, v. 2008/3; Bruker Analytical X-ray: Madison, WI, Additional data not shown in the manuscript are provided in Figure S1 and Tables S1-S3 for FMOF-1 2Toluene, and Figures S2-S3 and Tables S4-S6 for FMOF- 2 4Toluene. For the FMOF-1 2Toluene structure, toluene molecules were found disordered in two positions and refined accordingly with distance constraints. The occupancy factors of the two solvent molecules were close to 0.25 from initial structure 3

4 refinement. These values were fixed to 0.25 in the final structure refinement to give the formula Ag 2 [Ag 4 (Tz) 6 ] 2Toluene for FMOF-1 2Toluene. In the FMOF-2 4Toluene, the toluene molecules were disordered in two positions with occupancy factors close to 0.50 from initial structure parameters and were refined with constrained distances. III. Water Stability Analysis: The water stability of FMOF-1 was examined by water adsorption isotherms (Figure 1 in the main manuscript), single crystal X-ray diffraction, and infrared spectroscopy. The water adsorption isotherm of FMOF-1 reveals that FMOF-1 is water stable and no water molecules can enter into its voids. To confirm this, we have carried out single crystal X-ray diffraction using a water-soaked single crystal of FMOF-1. The evacuated single crystal of FMOF-1 was soaked in distilled water for several days before collecting data on a Bruker SMATR APEX2 CCD-based X-ray diffractometer. The XRD pattern of water-soaked FMOF-1 is essentially identical to that of the water untreated sample, indicating that the porous structure of FMOF-1 is retained after water treatment and that no water molecules are entrapped into the channels or cages of FMOF-1 (Figures S4-S5 and Tables S7-S10). The IR spectra were collected using a Nicolet 6700 FT-IR spectrometer equipped with a KBr beamsplitter. The Micro Well Plate accessory has an embedded DTGS detector, for data collection via transmission. The sample plate itself was made from a rectangle of silicon subdivided into cells by a PTFE mask. The experiment setup and data collection were driven by the Array Automation add-in to the OMNIC spectroscopy software. Processing via a discriminant analysis using TQ Analyst within Array Automation allowed the differences in the spectra to be brought out consistently. The FT- 4

5 IR spectrum was obtained over a frequency between 350 and 4000 cm -1. The spectra (Figure S6) were collected using 128 scans at 4 cm -1 resolution. As shown in Figure S6, no O-H stretching signals were observed for the water-treated FMOF-1 sample above 3200 cm -1 (which are usually strong bands in presence of any moisture). IV. Thermogravimetric analysis (TGA): The thermal stability of FMOF-1 and its toluene solvate was examined by TGA in combination with single crystal X-ray diffraction. TGA measurements were run for solvated and unsolvated crystals using a TGA-Q50 thermogravimetric analyzer from TA Instruments. Under an air atmosphere, TGA of toluene soaked FMOF-1 (Figure S7) reveals a weight loss of ~ 13% from 30 to 125 C, corresponding to 8 toluene molecules per unit cell, consistent with the toluene vapor adsorption data shown in Figure 1b in the main manuscript. There is no further weight loss from 125 to 300 C (Figure S7). Upon further heating, the obvious weight loss above 310 C corresponds to the sublimation and decomposition of FMOF-1. At 400 C, the overall weight loss of 85% for FMOF-1 indicates partial evaporation and decomposition. The guest molecules in FMOF-1 can be easily removed by heating at 100 C under vacuum for 1 h, which can be verified by TGA on the unsolvated FMOF-1. The fully unsolvated FMOF-1 form exhibits no obvious weight loss from 30 to 300 C (Figure S8). 5
