Two new bioactive silver–organic frameworks [Ag(μ3-PTAS)]n(NO3)n·nH2O (1) and [Ag4(μ4-PTAS)(μ5-PTAS)(μ2-SO4)2(H2O)2]n·2nH2O (2) were easily assembled, thus opening up the application of PTAS as a versatile N,S-building block in the crystal engineering of MOFs. The obtained products reveal infinite 3D networks driven by multiply bridging PTAS spacers that adopt unprecedented N2S-coordination modes. The topological analysis of 1 discloses an uninodal 3-connected net with the srs (SrSi2) topology, whereas 2 features a pentanodal 3,4,5-connected net with a hitherto undocumented topology. Apart from representing the first MOFs derived from PTAS, the compounds 1 and 2 display notable antibacterial and antifungal activities.

PTAS 作为多功能 N、S 构建模块在 MOF 晶体工程中的应用。所获得的产物显示了由多桥
PTAS 间隔物驱动的无限三维网络,这些间隔物采用了前所未有的
N2S 配位模式。对 1 的拓扑分析表明,它是一个具有 srs(SrSi2)拓扑结构的非odal 3 连接网络,而 2 则具有迄今为止尚未记录的拓扑结构,是一个五odal 3,4,5 连接网络。化合物 1 和 2 不仅是首批从
PTAS 衍生出的 MOFs,还具有显著的抗菌和抗真菌活性。
