Abstract:

Two novel 2D coordination polymers, [Co(BPDC)DMSO]·DMSO(1)(BPDC=2,2'-bipyridyl-4,4'-dicar- boxylic acid) and [Zn(BPDC)DMF]·DMF(2), were synthesized from 2,2'-bipyridyl-4,4'-dicarboxylic acid ligand (H2BPDC) under solvothermal conditions. Single crystal X-ray diffraction analyses reveal that compound 1 crystallizes in orthorhombic system and Pca21 space group with a=1.29628(13) nm, b=1.13721(13) nm, c=1.66457(19) nm, α=90°, β=90°, γ=90°, V=2.4538(5) nm3. Compound 2 crystallizes in monoclinic system and P21/c space group with a=0.9429(6) nm, b=1.4757(10) nm, c=1.5980(9) nm, α=90°, β=114°, γ=90°, V=2.030(2) nm3. Compounds 1 and 2 exhibit two different 3-connected hcb and fes topologies, respectively. The structures of the two compounds both contain interesting characters of double-helical chains(left- and right-handed helical chains). Additionally, the magnetic and luminescent properties of the two compounds were studied.
