本文报道了一种新的微孔金属有机骨架，即[Zn(2)(L)(btc)(Hbtc)] [NH(2)(CH(3))(2)]·(DMF)(2)(H(2)O)(4) (1)，它是通过Zn(NO(3))(2)自组装溶剂(氢)热合成的， N(4),N(4)-二(吡啶-3-基)-[1,1'-联苯]-4,4'-二甲酰胺(L)和1,3,5-苯三甲酸(H(3)btc)。其拓扑结构可以描述为包含四面体金属和配体节点的四连接 4(2)6(4) 矩阵。有趣的是，这样的矩阵与众所周知的方钠石 (SOD) 网络具有相同的拓扑符号，但 434 的 td10 与 SOD 网络的 791 的 td10 不同，表明这是一种特殊的四连接 4(2)6(4) 网络。另一个突出点是 CO(2) 对 N(2) 的高选择性吸附，这可能是由于带电骨架、1 中 -CONH- 和 -COOH 官能团的存在的综合作用所致。
Reported here is a new microporous metal-organic framework, namely [Zn(2)(L)(btc)(Hbtc)] [NH(2)(CH(3))(2)]·(DMF)(2)(H(2)O)(4) (1), which is synthesized solvo(hydro)thermally by the self-assembly of Zn(NO(3))(2), N(4),N(4)-di(pyridin-3-yl)-[1,1'-biphenyl]-4,4'-dicarboxamide (L) and 1,3,5-benzenetricarboxylate acid (H(3)btc). Its topology can be described as a four-connecting 4(2)6(4) matrix containing both tetrahedral metal and ligand nodes. Interestingly, such a matrix has the same topology symbol as that observed in the well known sodalite (SOD) net, but the td10 of 434 is different from the td10 of 791 for the SOD net, indicative of an exceptional four-connecting 4(2)6(4) net. Another outstanding point is the highly selective adsorption of CO(2) over N(2), possibly contributed by a combined effect from the charged skeleton, the existence of functional groups of -CONH- and -COOH in 1.
