摘要:
A 3d-4f coordination polymer {[NiTb 2(INAIP) 4(H 2O) 6]· 8H 2O} n (1) was obtained by hydrothermal assembly of NiSO 4·6H 2O and Tb(NO 3) 3·6H 2O with the H 2INAIP ligand. Complex 1 crystallizes in triclinic, space group P1 with a =1.009 72(5) nm, b = 1.083 43(5) nm, c =2.983 63(14) nm, V=3.209 3(3) nm 3, Z=2, C 56H 60NiTb 2N 8O 34, M r= 1765.67, D c=1.827 g·cm -3, μ=2.575 mm -1, F(000)=1 764, R int=0.031 5, R=0.0525, wR =0.131 8. Single-crystal X- ray diffraction analysis reveals that each INAIP 2- ligand uses its two carboxyl groups to connect two/three Tb(III) centers, and the Ni(II) only bonds to one pyridyl group and terminal water molecules, forming a two-dimensional (2D) bilayer. On the other hand, the 2D layers are further connected by hydrogen bonding interactions to give a three-dimensional (3D) supramolecular structure. The complex 1 at room temperature shows typical green photoluminescence of rare earth Tb 3+ ion.

The novel complex [Zn_2(Mba)_3(Phen)_2EtOH)]·ClO_4 (Hmba=methoxybenzoic acid, Phen=1,10-phenanthroline, EtOH=ethanol) was synthesized by hydrothermal reactions, and its structure was determined by X-ray diffraction. The crystal belongs to the triclinic system, space group Pi with a=1.15362(1), b=1.3655(3), c=1.61451(1) nm, α=72.842(2), β=83.259(3), γ=72.083(2)°, V=2.3112(6) nm3, Z=2, μ(MoKα)=11.71 cm~(-1), F(000)=1120, R=0.0552 and wR=0.1157 (I > 2σ(I)). The two centric zinc(Ⅱ) ions in the complex locate in a distorted octahedral coordination geometry and a distorted trigonal bipyramid coordination geometry, respectively. Two bridging bidentate carboxyl groups and a μ_2-O carboxyl group from three methoxybenzoic acids act as the bridge to link two Zn(Ⅱ) ions. The asymmetric units are connected by π-π packing interactions between aromatic rings to form a three-dimensional supramolecular network. The experimental results show a good fluorescence property for the complex.

A new 3d-4f coordination polymer {[CuTb 2(INAIP) 3(HCOO)(H 2O) 3] · 3H 2O} n (1) was obtained by solvothermal assembly of CuCl 2·H 2O and Tb(NO 3) 3·6H 2O with the H 2INAIP (5-(isonicotinamido)isophthalic acid) ligand. Complex l crystallizes in triclinic, space group P1̄ with a=1.088 79(16) nm, b = 1.518 5(2) nm, c = 1.565 3(2) nm, D=2.338 1(6) nm 3, Z=2, C 43H 37CuTb 2N 6O 23,M r=1387.17, D c=1.970 g·cm -3,μ=3.538 mm -1, F(000)=1360,R int=0.021 2, R=0.058 9, wR =0.129 2. Single-crystal X-ray diffraction analysis revealed that each INAIP 2- ligand uses its two carboxyl groups to connect two or three Tb(III) ions into 2D lanthanide bi-layer structure. Then the 2D layers are further connected by pyridyl groups to give a three-dimensional (3D) pillared-layer structure. In addition, the luminescent property of complex 1 has been investigated at room temperature, and showed the obviously green photoluminescence in it. CCDC: 881422.
摘要:
A cobalt coordination polymers [Co(dib)(SO 4) (1) was obtained by solvothermal assembly of CoSO 4·7H 2O with sodium formate in the presence of N-donor ligands, namely 1,4-di(1-imidazolyl) benzene (dib). Compound 1 crystallizes in monoclinic system, space group C2/ c with a=1.972 26(7) nm, b=0.977 0(3) nm, c=1.1839 6(4) nm, β=96.479(2)°, V=2.266 8(13) nm 3, Z=4, C 24H 20N 8CoO 4S, M r=575.47, D c=1.686 g·cm -3, μ=0.903 mm -1, F(000)=1 180, R int=0.018 3, R=0.024 6, wR=0.072 6. Single-crystal X-ray diffraction analysis revealed that each dib ligand in turn uses its two imidzole groups to connect two metal centers, then the two-dimensional (2D) layer is formed. On the other hand, the 2D layers are further connected by sulfate to give a three-dimensional (3D) pcu topologic structure. In addition, the magnetic property of complex 1 has been investigated in the temperature range of 1.8~300 K, and the results show the weak antiferromagnetic interactions between Co(II) ions bridged by sulfate.

摘要:
A new trinuclear complex Mn3(2,2ʹ-bipy)2(C7H5O3)6 (1) with α-furacrylic acid (HL) and 2,2ʹ- bipyridine as ligands has been synthesized. In 1, six L- anions link three Mn(II) cations to form a trinuclear structure. Each Mn cation is coordinated by six atoms to give a distorted octahedral coordination geometry. The luminescence and electrochemical properties of 1 were investigated. Complex 1 exhibits one intense fluorescence emission band at around 498 nm. It is paramagnetic showing weak antiferromagnetic coupling at low temperature. The electron transfer is irreversible in the electrode reaction of 1, one electron being involved in the reduction corresponding to Mn(III)/Mn(II).
