Coordination Polymers with 2D 3D Interdigitated Arrays Based on 5-(4-(1H-1,2,4-Triazol-1-yl)phenyl)-1H-tetrazole: Syntheses, Structures, and Properties

摘要

The interdigitated coordination networks [Cu(tyty)] (1) and [Cu-1.5(L1)(L2)(tyty)] (2) [Htyty = 5-(4-(1H-1,2,4-triazol-1-yl)phenyl)-1H-tetrazole, HL1 = 2,3,4,5-tetrachlorobenzoic acid, HL2 = 2,3,4,5,6-pentachlorobenzoic acid], were hydrothermally synthesized and further characterized by single-crystal X-ray diffraction, powder X-ray diffraction, elemental analyses, IR and UV/Vis spectroscopy, and TG analyses. Compound 1 consists of unique 2D double-bilayers, which are interdigitated by adjacent 2D double-bilayers to yield a 2D 3D interdigitated framework. Compound 1 is the first example of a coordination polymer containing double-bilayer motifs. Compound 2 exhibits a new 2D 3D interdigitated network, which is assembled from sidearm-containing 2D layers that are formed by tyty anions and rod-shaped secondary building units. The magnetic properties of 2 were also investigated.
