Construction of a ytterbium supramolecular compound from 5,5′-(buta-diyne-1,4-diyl)diisophthalic acid

Abstract

A novel 3D ytterbium supramolecular compound, [Yb(HBDDC)(H2O)4]·2H2O(1), was synthesized via 5,5′-(buta-diyne-1,4-diyl)diisophthalic acid ligand(H4BDDC) under solvothermal conditions. Single-crystal X-ray diffraction analysis reveals that compound 1 crystallizes in triclinic system, $P\bar 1$ space group with a=0.71372(14) nm, b=1.0566(2) nm, c=1.7969(4) nm, α=101.01(3)°, β=98.15(3)°, γ=99.17(3)° and V=1.2922(4) nm3. Compound 1 exhibits a special infinite 1D chain, which stacks parallel each other in an ABAB sequence, leading to the formation of a 3D supramolecular structure owing to the strong π-π interactions between adjacent phenyl ring groups. Moreover, compound 1 manifests excellent luminescent property.
