In the utilization of three ditopic ligands with different bend angles as pillars, we reported herein three pillar-layered Zn-triazolate-carboxylate frameworks, namely, [Zn-2(ATRZ)(2)(BDC)](n) (1), [Zn-2(ATRZ)(2)(TPDC)](n)center dot 2nDMF (2) and [Zn-2(ATRZ)(2)(ADDC)](n) (3) (ATRZ = 3-amino-1,2,4-triazole, H2BDC = 1,4-benzenedicarboxylic acid, H2TPDC = 2,5-thiophenedicarboxylic acid, and H(2)ADDC = 1,3-adamantanedicarboxylic acid). Single crystal structural analyses demonstrate that different geometries of ditopic carboxylate pillars not only result in Zn-ATRZ layers adopting various corrugated configurations, but also give rise to 3,4-connected self-interpenetrated net of If and non-interpenetrated nets of 2 and 3. All these compounds exhibit high thermal stability and blue photoluminescence. (C) 2015 Elsevier B.V. All rights reserved.
