摘要

A 3-D supramolecular framework, [Er(pybz)₂(Hnds)(H ₂O)₂]-H₂O (1, Hpybz = 4- pyridin-4-yl-benzoic acid, H₂nds = naphthalene-1, 5-disulfonic acid), based on lanthanide ions and mixed ligands has been hydrothermally synthesized. The structure was determined by single- crystal X-ray diffraction and further characterized by IR, elemental analysis and thermogravimetric analysis. Compound 1 crystallizes in the monoclinic system, space group P2₁/n with a = 9.849(2), b = 22.526(5), c = 17.167(4) Å, β =105.461(4)° and V= 3670.9(2) Å³. In 1, two seven-coordinated Er³⁺ ions are bridged by two pybz ligands to form a dimeric [Er₂(COO)₂] unit, which is further orderly linked by carboxyl of pybz" ligand to obtain a 1-D chain running along the a axis. Interestingly, significant H-bonding and π-π stacking interactions link the neighboring parallel chains leading to a 3-D supramolecular network structure which displays 1-D rhombus open channels (17.2Å × 22.5Å).
