Abstract

Abstract: Two 2, 6‐bis(2‐pyrazin‐2‐yl)‐4‐(4‐(tetrazol‐5‐yl)phenyl)pyridine (HL1 )‐based transition metal complexes, {[Zn(L1 )(L2 )0.5 ]⋅H2 O} n (1 ) and [Zn3 (H2 O)2 (L1 )2 (L3 )] n (2, H2 L2 =2, 5‐dihydroxyterephthalic acid, and H4 L3 =pyromellitic acid) have been solvothermally synthesized by varying the substitutes appended on phenyl‐based dicarboxylate coligands. The tetragonal pyramidal Zn II ions in 1 are periodically extended by two deprotonated L1 − and one L2 2− connectors, resulting in the first L1 − ‐derived three‐fold interpenetrating wrinkle layer. By contrast, the C 2 ‐symmetric {Zn3 (COO)2 } clusters in 2 are periodically bridged by centrosymmetric L3 4− and bulky L1 − connectors, leading to a four‐connected diamond framework. Apparently, the replacement of two hydroxyl groups by a carboxylate pair in the coligands has significantly achieved the manipulations on both the motif and dimensionality of the terpyridine‐derived metal complexes. Furthermore, the both samples exhibit strong thermal stability and efficient L1 − ‐dominated light‐responsive ability. Abstract :
