摘要
Eight coordination polymers constructed from divalent metal salts, N,N ′ -bis(pyridin-3-ylmethyl)terephthalamide (L), and various dicarboxylic acids are reported, affording [Co(L)(5-ter-IPA)(H 2 O) 2 ] n (5-tert-H 2 IPA = 5-tert-butylisophthalic acid), 1, {[Co(L)(5-NO 2 -IPA)]⋅2H 2 O} n (5-NO 2 -H 2 IPA = 5-nitroisophthalic acid), 2, {[Co(L) 0.5 (5-NH 2 -IPA)]⋅MeOH} n (5-NH 2 -H 2 IPA = 5-aminoisophthalic acid), 3, {[Co(L)(MBA)]⋅2H 2 O} n (H 2 MBA = diphenylmethane-4,4′–dicarboxylic acid), 4, {[Co(L)(SDA)]⋅H 2 O} n (H 2 SDA = 4,4-sulfonyldibenzoic acid), 5, {[Co 2 (L) 2 (1,4-NDC) 2 (H 2 O) 2 ]⋅5H 2 O} n (1,4-H 2 NDC = naphthalene-1,4-dicarboxylic acid), 6, {[Cd(L)(1,4-NDC)(H 2 O)]⋅2H 2 O} n , 7, and {[Zn 2 (L) 2 (1,4-NDC) 2 ]⋅2H 2 O} n , 8, which were structurally characterized by using single-crystal X-ray diffraction. The structural types of 1–8 are subject to the metal and ligand identities, showing a 2D layer with the hcb, a 3D framework with the pcu, a 2D layer with the sql, a polycatenation of 2-fold interpenetrated 2D layer with the sql, a 2-fold interpenetrated 2D layer with the 2,6L1, a 3D framework with the cds, a 2D layer with the 2,4L1, and a 2D layer with the (10 2 ⋅12)(10) 2 (4⋅10⋅12 4 )(4) topologies, respectively. The investigation on the photodegradation of methylene blue (MB) by using complexes 1–3 reveals that the degradation efficiency may increase with increasing surface areas.
