The introduction of various secondary N-donor ligands into an in situ ditetrazolate-ligand synthesis system of terephthalonitrile, NaN{sub 3} and ZnCl{sub 2} led to the formation of three new entangled frameworks Zn(pdtz)(4,4'-bipy).3H{sub 2}O (1), [Zn(pdtz)(bpp)]{sub 2}.3H{sub 2}O (2) and Zn(pdtz){sub 0.5}(N{sub 3})(2,2'-bipy) (3) (4,4'-bipy=4,4'-bipyridine; bpp=1,3-bis(4-pyridyl)propane; 2,2'-bipy=2,2'-bipyridine; H{sub 2}pdtz=5,5'-1,4-phenylene-ditetrazole). The formation of pdtz{sup 2-} ligand involves the Sharpless [2+3] cycloaddition reaction between terephthalonitrile and NaN{sub 3} in the presence of Zn{sup 2+} ion as a Lewis-acid catalyst under hydrothermal conditions. Compound 1 exhibits a fivefold interpenetrating 3D framework based on the diamondoid topology. Compound 2 displays a twofold parallel interpenetrating framework based on the wavelike individual network. Compound 3 possesses a 2D puckered network. These new Zn-ditetrazolate frameworks are highly dependent on the modulation of different secondary N-donor ligands. Their luminescent properties were investigated. - Graphical abstract: Three new entangled frameworks were prepared by an in situ ditetrazolate-ligand synthesis system assisted with various auxiliary N-donor ligands. The entangled structures can be modulated by different secondary ligands.
