Self assembly of Cu(2+) with the multifunctional ligand 2-(4-pyridyl)thiazole-4-carboxylic acid (Pytac) affords the neutral 3D coordination polymer Cu(3)(Pytac)(6)(14) (hereafter, SZL-1), which has the rare moganite topology. The mineral moganite has a topology that is closely related to the well-known quartz topology, but the two topologies are differentiated by the number of topologically inequivalent nodes. Whereas only one kind of node is present in quartz, two types of topologically inequivalent nodes are present in moganite. The title compound, which has three vertices in its repeat unit, has two types of topologically inequivalent nodes with the overall vertex symbol (4(2)x6(2)x8(2))(4x6(4)x8)(2) corresponding to the moganite net. Prior to this report, few metal-organic framework materials (MOFs) have been found to contain more than one type of node, and SZL-1 is the first MOF with the moganite topology.
铜离子(Cu(2+))与多功能配体2-(4-吡啶基)噻唑-4-羧酸(Pytac)自组装得到中性三维配位聚合物Cu(3)(Pytac)(6)(14)(以下简称SZL-1),其具有罕见的莫来石拓扑结构。莫来石矿物的拓扑结构与著名的石英拓扑结构密切相关,但这两种拓扑结构通过拓扑不等价节点的数量来区分。石英中仅存在一种节点,而莫来石中存在两种拓扑不等价节点。标题化合物在其重复单元中有三个顶点,具有两种拓扑不等价节点,其整体顶点符号为(4(2)x6(2)x8(2))(4x6(4)x8)(2),对应于莫来石网络。在本报告之前,很少发现金属有机框架材料(MOF)包含不止一种类型的节点,SZL-1是首个具有莫来石拓扑结构的MOF。
