| 1 | A New Cd(Ⅱ) Coordination Polymer Constructed by 1,10-Phenanthroline Derivative: Syntheses, Structure, Physical Properties and Theoretical Calculation显示文摘A new Cd(Ⅱ) coordination polymer, [Cd(L)2(H2O)]n(1), has been hydrothermally synthesized by using 1-(1 H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)naphthalen-2-ol(HL),(3-(4-(carboxymethoxy)phenyl)acrylic acid and Cd(NO3)·4 H2O. It crystallizes in monoclinic, space group P21/c with a = 19.41(2), b = 11.078(12), c = 20.09(2)A, β = 116.824(17)°, V = 3855(7)A^3, Z = 4, C46H28CdN8O3, Mr = 853.17, Dc = 1.470 g/cm^3, F(000) = 1728, μ(Mo Ka) = 0.621 mm^-1, R = 0.0338 and wR = 0.0890. 1 shows a one-dimensional(1D) zigzag chain structure. The neighboring chains are extended into a two-dimensional(2D) layer structure by π-π interactions between adjacent L ligands. In addition, Natural Bond Orbital(NBO) analysis was performed by the B3LYP/LANL2DZ method in Gaussian 09 Program. The calculation results show the obvious covalent interaction between the coordinated atoms and Cd(Ⅱ) ion. | 孔治国 韩倩 张璐 刘东雪 胡波 王秀艳 | 2019 | Chinese Journal of Structural Chemistry2019，38，12： | 2 |
| 2 | A New Co(Ⅱ) Coordination Polymer Based on a Flexible 1,4-Cyclohexanedicarboxylic Acid: Synthesis, Structure and Thermal Behavior显示文摘A new Co(Ⅱ) coordination polymer, [Co(1,4-chdc)(L)(H2O)]n(1), was synthesized under hydrothermal condition(1,4-H2chdc = 1,4-cyclohexanedicarboxylic acid, L = 2-(4-fluoro-phenyl)-1 H-imidazo[4,5-f][1,10]phenanthroline). Its crystal structure was determined by single-crystal X-ray diffraction. 1 crystallizes in triclinic, space group P1 with a = 8.790(5), b = 10.486(5), c = 13.305(5)A, α = 87.391(5), β = 82.925(5), γ = 81.841(5)°, V = 1204.2(10)A^3, Z = 2, C27H23FN4O5Co, Mr = 561.42, Dc = 1.548 g/cm^3, F(000) = 578, μ(Mo Ka) = 0.769 mm^-1, R = 0.0415 and wR = 0.1043. In 1, each 1,4-chdc anion bridges two neighboring Co(Ⅱ) atoms to give a chain structure. The L ligands are attached on one side of the chain through chelating the Co(Ⅱ) atoms, and are stacked with those of an adjacent chain through π-π interactions, yielding a double-chain structure. The double-chain structures are linked into a supramolecular layer structure through N–H…O hydrogen-bonding interactions between the adjacent double-chain structures. Moreover, the thermal behavior of 1 was also studied. | 王秀艳 李聪 邹春凯 阚若飞 张晓旭 徐占林 | 2019 | Chinese Journal of Structural Chemistry2019，38，12： | 2 |
| 3 | Two New Coordination Complexes Based on 2,2'-H2biimidazole: Synthesis, Structure, Luminescent Property and Theoretical Calculation显示文摘Two new coordination complexes[Cd(L)2(1,2,3-HBTC)]·3H2O(1)and{[Zn(L)(1,2-BDC)]-H2O}n(2)were synthesized under hydrothermal conditions(1,2,3-H3 BTC=1,2,3-tricarboxybenzene,1,2-H2 BDC=1,2-dicarboxybenzene and L=2,2’-H2 biimidazole).1 crystallizes in monoclinic,space group P21/c with a=12.256(5),b=11.620(5),c=17.479(5)A,β=95.548(5)°,V=2477.6(16)A^3,Z=4,C21H22N8 O9 Cd,Mr=642.86,Dc=1.724 g/cm^3,F(000)=1296,μ(MoKa)=0.950 mm^-1,R=0.0546 and wR=0.1724.2 belongs to the monoclinic system,space group P21/c with a=7.408(4),b=20.743(10),c=10.194(5)A,β=95.648(6)°,V=1477.3(12)A^3,Z=4,C14H12N4 O5 Zn,Mr=381.65,Dc=1.716 g/cm3,F(000)=776,μ(MoKa)=1.698 mm^-1,R=0.0574 and wR=0.1632.The central Cd(Ⅱ)ion in 1 is coordinated with five atoms,forming a slightly distorted square-pyramidal geometry.The central Zn(Ⅱ)ion in 2 is four-coordinated by two nitrogen atoms from one L ligand and two oxygen atoms from two different 1,2-BDC anions.In addition,luminescent property of 1 has been investigated,and natural bond orbital(NBO)analysis of 2 has been calculated by the B3LYP/LANL2DZ method. | ZHANG Hua XU Tongtong XING Tianyi WANG Xueying ZUO Jiamei KONG Zhiguo | 2020 | Chinese Journal of Structural Chemistry2020，39，8： | 1 |
