摘要
Abstract A pair of two-dimensional (2D) isostructural coordination polymers (CPs), {[Co(2,3-qldc)(H 2 O)]} n ( 1 ) and {[Mn(2,3-qldc)(H 2 O)]} n ( 2 ), where 2,3-H 2 qldc = quinoline-2,3-dicarboxylic acid, were hydrothermally synthesized and characterized through IR spectroscopy, elemental and thermal analysis, power X-ray diffraction, and single-crystal X-ray diffraction. The results have revealed that the fully deprotonated 2,3-H 2 qldc ligand connects the Co(II)/Mn(II) atoms with a μ 3 -bridge to form a square-wave 2D network, which is further extended into 3D stacks through O–H···O, C–H···O hydrogen bonds and π···π stacking interactions. Topologically, 1 or 2 can be simplified as a 4-connected sql type with a Schläfli symbol {4 4 ·6 2 } and a Shubnikov tetragonal plane net, or as a 3-connected fes type with a Schläfli symbol {4·8 2 } and a Shubnikov plane net. The thermal stability and the solid state fluorescence properties of 1 and 2 were investigated.
