"Based off this passage, identify if the MOF called ""MOF-37"" is stable or unstable in water. Note, there may not be enough information to provide an answer: ""MOF-37: A mixture of 2,6- naphthalenedicarboxylic acid (H2NDC; 0.040 g, 0.20 mmol) and Zn(NO3)2‚6H2O (0.059 g, 0.20 mmol) was dissolved in N,N′-diethylformamide (DEF, 5 mL) and chlorobenzene (ClBz, 5 mL). This vial was inserted in a larger vial containing DEF (2 mL), ClBz (2 mL),
and triethylamine (0.15 mL). The larger vial was sealed and left
undisturbed for 7 days to crystallize. The colorless crystals were filtered
and washed with 3 × 10 mL of DEF and ClBz and left to air-dry,
yielding 0.038 g (41% based on H2NDC). This material is insoluble in
water and common organic solvents such as methanol, ethanol, acetone,
acetonitrile, DMF, and dimethyl sulfoxide. """,Stable,Unstable,Not enough information,A,Materials,Easy,Advanced Reasoning,Water Stability Argument Mining,10.1021/ja010825o
"Based off this passage, identify if the MOF called ""Al-PyrMOF/m8o67"" is stable or unstable in water. Note, there may not be enough information to provide an answer: ""The ability of these materials to capture CO2 from wet flue gases is of important practical concern. We therefore used a breakthrough experiment to determine the capture capacity of both Al-PMOF and Al-PyrMOF for a mixture of CO2/N2 under dry- and humid-conditions24 (Fig. 4e). These results confirm the predictions of the simulations (Extended Data Fig. 7): humidity in the flue gases has only a minimal influence on the capture capacity of Al-PMOF, whereas for Al-Pyr- MOF the capture capacity is in fact enhanced.""",Stable,Unstable,Not enough information,A,Materials,Hard,Advanced Reasoning,Water Stability Argument Mining,10.1038/s41586-019-1798-7
"Based off this passage, identify if the MOF called ""Al-PyrMOF/m8o67"" is stable or unstable in water. Note, there may not be enough information to provide an answer: ""Figure 2a shows that m8o67 is resistant to H2O
flooding: even at a relative humidity of approximately 85%, we find
that H2O has only a small effect on CO2 capacity. Conversely, m8o71
completely loses its CO2 capacity at 60% relative humidity (Fig. 2b).
In Fig. 2c, d we visualize the hydrogen-bond network that is formed at
100% relative humidity in both materials""",Stable,Unstable,Not enough information,B,Materials,Hard,Advanced Reasoning,Water Stability Argument Mining,10.1038/s41586-019-1798-7
"Based off this passage, identify if the MOF called ""3-NiMeOH"" is stable or unstable in water. Note, there may not be enough information to provide an answer: ""In principle, these phenomena, especially for 3-NiMeOH,
may be ascribed to the different reorientation processes of the
highly disordered guest molecules during slow cooling and
quenching treatments. Similar properties have been known for
water, which on quenching forms amorphous ice denser than
ordinary crystalline ice.""",Stable,Unstable,Not enough information,C,Materials,Medium,Advanced Reasoning,Water Stability Argument Mining,10.1039/c3sc22222e
"Based off this passage, identify if the MOF called ""Ba2(EDTA).2.5H2O"" is stable or unstable in water. Note, there may not be enough information to provide an answer: ""The dehydration behavior of Ba2(EDTA)·2.5H2O was studied in more detail. The TG curve (Figure 3a) as well as the crystal structure (Figure 2d) suggest that a crystalline anhydrous phase might exist with a crystal structure closely related to the crystal structure of Ba2(EDTA)·2.5H2O but different from Ba2(EDTA) (Figure 1d). Actually, the powder X-ray diffraction pattern of a dehydrated sample (250 °C) is closely related to the pattern recorded for Ba2(EDTA)·2.5H2O and could be indexed with a tetragonal primitive unit cell (tP, a = 19.226(10) Å, c = 8.986(3) Å, V = 3335.4(3) Å3, ΔV = - 154.6 Å3). Subsequent experiments also showed that the crystal structure of Ba2(EDTA)·2.5H2O is fully recovered (PXRD) when the dehydrated product is stored in humid air for one week (tP, a = 19.7317(24) Å, c = 8.9743(13) Å, V = 3494.1(9) Å3). Shorter exposure times (5 h, 24 h, 3 d) lead to partial rehydration as proven by TG measurements.""",Stable,Unstable,Not enough information,A,Materials,Medium,Advanced Reasoning,Water Stability Argument Mining,10.1002/zaac.201000044

"Based off this passage, identify if the MOF called ""MOF-74"" is stable or unstable in water. Note, there may not be enough information to provide an answer: ""In contrast to the weakly assembled chains in MOF-69A described above, the chains in MOF-74 are expected to be extremely robust owing to only edge-sharing between metals as well as coordination to two types of functional group on each linker. When solvated, all Zn ions in MOF-74 are 6-coordinate, and therefore it is expected that the zinc-oxygen bonds of the linkers will be less susceptible to displacement by incoming water molecules. Nevertheless, MOF-74 is predicted, and experimentally determined, to possess good stability toward reaction with water.""",Stable,Unstable,Not enough information,A,Materials,Medium,Advanced Reasoning,Water Stability Argument Mining,10.1021/ja9061344
