Solvothermal synthesis has produced two new crystal structures derived from the Zn–terephthalic acid–DMF system. The major synthesis product is the metastable Zn(C8H4O4)(C3H7NO), 1, which converts completely over a period of 12 months to the known crystalline phase MOF-2, the phase obtained by crystallization at ambient conditions [19,21]. Thus, solvothermal synthesis in this MOF system produces metastable products under kinetic control. An additional phase, Zn(HCO2)3(C2H8N), 2, is also produced, derived from decomposition of the DMF moieties, demonstrating clearly the risks for undesired reactant decomposition under these solvothermal condi- tions. The phase 2 is stable over the 12-month period. The study demonstrates that MOF syntheses can produce not only multiple crystal structures under different conditions, but also numerous different structures, including some that are metastable, under identical conditions. |

| 溶劑熱合成法已產(chǎn)生了兩個(gè)新的衍生于對(duì)苯二甲酸鋅-DMF系統(tǒng)的晶體結(jié)構(gòu)。 主要合成產(chǎn)物為亞穩(wěn)態(tài)的Zn(C8H4O4) (C3H7NO), 1,該產(chǎn)物在12月期間內(nèi)完全地轉(zhuǎn)化為已知的晶相MOF-2,得到的這種晶相在環(huán)境條件下進(jìn)行結(jié)晶[19,21]。因而,動(dòng)態(tài)控制下于MOF系統(tǒng)中溶劑熱合成法產(chǎn)生了亞穩(wěn)態(tài)的產(chǎn)物。 也產(chǎn)生了衍生于二甲基甲酰胺分子的某部分的另外的一種相,Zn(HCO2)3(C2H8N),2,這清楚地表明了在這種溶劑熱條件下不期望的反應(yīng)物分解風(fēng)險(xiǎn)的存在。 相2在12個(gè)月期間內(nèi)是穩(wěn)定的。這種研究表明MOF合成不僅會(huì)于不同條件下產(chǎn)生多種晶體結(jié)構(gòu)而且還會(huì)在相同條件下產(chǎn)生許多的不同的結(jié)構(gòu),包括某些亞穩(wěn)態(tài)的結(jié)構(gòu)。 |
