Syntheses, crystal structures, and properties of various one- dimensional coordination polymers based on macrocyclic metallic tectons and dicarboxylic acid ligand

摘要

The reaction of different macrocyclic metallic tectons and dicarboxylic acid ligand yielded six new coordination polymers, namely, {[(NiL1)(4,4'-Bpdc)] aEuro cent DMF aEuro cent 2.5H(2)O} (n) (I), {[(NiL2)(4,4'-Bpdc)] aEuro cent DMF aEuro cent 2.5H(2)O} (n) (II), [(NiL3)(2)(4,4'-Bpdc)(1.5)][(NiL3)(4,4'-Bpdc)] aEuro cent ClO4 aEuro cent 28H(2)O (III), {[(NiL4)(4,4'-Bpdc)] aEuro cent 4H(2)O} (n) (IV), {[(NiL5)(4,4'-Tpdc)] aEuro cent 5H(2)O} (n) (V), {[(NiL3)(4,4'-Tpdc)]} (n) (VI) (L-1 = 1,4,7,9,12,14-hexaaza-tricyclo[12.2.1.1(4.7)]octadecane, L-2 = 1,3,10,12,15,18-hexaazatetracyclo[16.2.1.1(12.15).0(4.9)]docosane, L-3 = 11-methyl-1,4,8,10,13,15-hexaaza-tricyclo[13.3.1.1(4.8)]icosane, L-4 = 1,3,10,12,16,19-hexaazate-tracyclo[17.3.1.1.(12.16),0(4.9)]tetracosane, L-5 = 1,4,8,10,13,15-hexaaza-tricyclo[13.3.1.1(4.8)]icosane, 4,4'-Bpdc = 4,4'-biphenyldicarboxylic acid and 4,4'-Tpdc = 4,4'-terphenyldicarboxylic acid) (CIF files CCDC nos. 1055545-1055550 for I-VI, respectively). Except for the different conformations of the macrocyclic metallic tectons or dicarboxylic acid ligands, complexes I-VI crystallized under the same environment, however, they exhibit diverse packing mode of infinite 1D coordination polymers, showing macrocyle or dicarboxylic acid ligand regulated self-assemble. The solid states UV-Vis for complexes I-VI also have been investigated.
