A hydrostable and bromine-functionalized MOF with a sxd topology constructed from tetranuclear clusters, {[Mn₂(Bript)₂(4,4'-bpy)_0.5(DMF)]∙(H₂O)}_n (1) (H₂Bript = 4-Bromoisophthalic acid, 4,4'-bpy = 4,4'-bipyridine, DMF = dimethylformamide) was synthesized and structurally characterized. TGA and PXRD results show high thermal and water stability for the framework. 1 displays a 3D framework with the channel of 4.6 × 4.6 Ų along the c axis. The framework exhibits a reversible and highly selective luminescent sensing function with respect to Hg²⁺ cation. Magnetic measurements reveal that the presence of weak antiferromagnetic couplings between the four Mn(II) ions in 1.

甲hydrostable和溴官能MOF具有SXD从四核簇，{[锰构建拓扑₂（Bript）₂（4,4'-联吡啶）_0.5（DMF）]∙（H ₂ O）} _Ñ（1）（H合成了₂ Bript = 4-溴间苯二甲酸，4,4'-bpy = 4,4'-联吡啶，DMF =二甲基甲酰胺）并对其结构进行了表征。TGA和PXRD结果表明该框架具有很高的热稳定性和水稳定性。1个显示具有4.6×4.6埃通道中的3D框架²沿Ç轴线。该框架相对于Hg ²⁺具有可逆和高度选择性的发光感应功能阳离子。磁性测量表明，1中的四个Mn（II）离子之间存在弱的反铁磁耦合。
