Two novel metal–organic frameworks of [M3(ptz)2(N3)4(H2O)2] (M = Zn(1), Cd(2)) (ptz = 5-(4-pyridyl)tetrazolate) have been prepared hydro(solvo)thermally by reactions of 4-cyanopyridine and excess NaN3 in the presence of zinc and cadmium chloride, respectively. The overall structure motif of complexes 1 and 2 show pillared layered frameworks and feature an unprecedented 3-nodal network with (3,5,6)-connectivity. The layer is of particular interest as it is constructed by μ1,1–N3− and μ1,1,3–N3− bridging modes, simultaneously. Furthermore, the solid fluorescent properties and TGA were studied.
Two isostructural complexes feature a novel 3D pillared layered structure which represents an uncommon example of a (3,5,6)-connected net with Schläfli symbol of (4.53.6.73.8.9)(42.54.62.74.93)(4.7.8)(4.5.6).Figure optionsDownload as PowerPoint slideHighlights
► Two pillared layered three-dimensional complexes have been synthesized.
► The layer is constructed by μ1,1–N3− and μ1,1,3–N3− bridging modes, simultaneously.
► The frameworks exhibit 3-nodal network with (3,5,6)-connectivity topology.
