Abstract
Two Cu(I) coordination polymers {[Cu
2(bibp)
2]×bdc×3H
2O}
n
(
1) and {[Cu
3(bib)
3]×btc×5H
2O}
n
(
2), where bibp = 4,4'-bis(1-imidazol-1-yl)biphenyl, H
2bdc = terephthalic acid, bib = 1,4-bis(1-imidazol-1-yl)benzene, H
3btc = benzene-1,3,5-tricarboxylic acid, are synthesized under solvothermal conditions and characterized structurally. Complex
1 crystallizes in the triclinic form with the space group
P-1, and Cu(1) is two-coordinated by two N atoms of bibp, Cu(2) is three coordinated from two N atoms of bibp and one water molecule. Complex
2 crystallizes in the triclinic form with the space group
P-1; the copper ions are monovalent and two-coordinated by two N atoms of bib. The bdc and btc ligands are not coordinated with Cu ions, but play important roles in the generation of a 3D supramolecular structure of complexes
1 and
2 via weak interactions respectively.
