Two 3D Ln-organic coordination frameworks（Ln = Pr3＋ for 1 and Er3＋ for 2） have been constructed. Single-crystal X-ray diffraction analysis reveals that the two complexes have similar structures and belong to the monoclinic C2/c space group. The trans-μ4-（η2：η1）-（η1：η1） 1,2-pda2- anions link the LnIII centers to generate a 2D network containing helical motif. The dimensionality is extended into a 3D architecture through cis-bis（μ2-η2：η1） 1,2-pda2- anions linking. The geometry of Ln3＋ ions is single-capped anti-square prism. Two complexes were characterized by IR spectra and thermogravimetric analysis. The solid fluorescence of 1 and 2 was also investigated at room temperature.

Two new coordination complexes, [Pr（1,3-pda）0.5（nbca）2（H2O）2]（1） and [Pr2（1,3-pda）3（2,2ˊ-bpy）2（H2O）2]（2）（H2pda = 1,3-phenylenediacetic acid, Hnbca = 5-nitro [1,1ˊ-biphenyl]-3-carboxylic acid, 2,2ˊ-bpy = 2,2ˊ-bipyridine）, have been synthesized under hydrothermal conditions and characterized by elemental analysis, IR spectra, and single-crystal X-ray diffraction. In 1, the nbca ligands bridge the Pr3＋ ions to form a 1D chain. Moreover, these 1D chains are united together through the 1,3-pda ligands to afford a 2D layer. In contrast, due to a different auxiliary ligand, complex 2 is a 2D layer linked through only bridging deprotonated 1,3-pda. Thermal stabilities and solid fluorescence properties of 1 and 2 were also studied.

Materials with high surface area,tailored pore size and good electrical conductivity are needed for improved supercapacitors(SCs).Metal-organic frameworks(MOFs)have high surface areas and tailored pore sizes.Here,the MOF(1)of[Ni3(μ3 OH)(pba)3(bpdc)1.5]·11.5 DMA·0.5 CH3 OH·7 H2O is good enough to result in electrode materials with nearly ideal supercapacitive behavior at the rate up to 50 mV·s^-1 in a KOH electrolyte.The super capacitive performance of MOF(1)was measured using cyclic voltammogram,galvanostatic discharge and electrochemical impedance spectroscopy measurements.This MOF(1)as electrode exhibits the highest super capacitive properties with 417 F·g^-1,the maximum storage energy and power density are 9.27 and 2.38 kW·kg^-1.The long term stability of MOF(1)as SCs is checked that the capacitance is decreased by 17%after 1000 cycles.

A new coordination polymer, [Mn(3,4-pybz)2]n·3(H2O)(1), has been hydrothermally synthesized from Mn Cl2·4H2O and an unsymmetrical 3-pyridin-4-yl-benzoic acid(3,4-Hpybz), and characterized by IR, elemental analysis, thermogravimetric analysis, and singlecrystal X-ray diffraction. In complex 1, each 3,4-pybz ligand represents a three-connected node to combine with the six-connected Mn(II) ions, generating a 3D binodal(3,6)-connected ant network. In addition, magnetic investigations reveal that complex 1 exhibits an antiferromagnetic behavior. According to the crystal structure, the full-geometrical optimization of complex 1 was carried out by using hybrid DFT methods at the B3LYP/6-31G(d) level. Meantime, the DFT-BS approach was applied to study the magnetic coupling behavior for complex 1, and the result reveals that the calculated exchange coupling constants J were in good agreement with the experimental data.
