摘要：
A novel one-dimensional chain coordination polymer of terbium(III) with p-methylbenzoic acid, 2,2′-bipyridine and 4,4′-bipyridine has been synthesized and characterized. The crystal data of this complex C 39H37N3O8Tb are as follows: monoclinic system, space group P21 / n, a=0.974 01(10) nm, b=2.605 8(3) nm, c=1.457 77(14) nm, β=96.108 (2)°, V=3.678 9 (6) nm 3, Dc=1.507 g·cm-3, M r=834.64, Z=4, μ, (Mo ATα)=1.978 mm-1, F (000)=1 684, R1= 0.032 4, wR2=0.063 4. The crystal structure of the complex shows that the terbium(III) ion is coordinated with eight oxygen atoms, six from five p-methylbenzoic acid molecules and two from two water molecules, respectively, forming the distorted tetraprism geometry. The luminescent property of the complex is also studied.

The title complex of copper(II) with m-chlorobenzoic acid, 1,10-phenanthroline (phen) and copper perchlorate has been synthesized and characterized in the solvent mixture of water and methanol. Crystal data for this complex: triclinic, space group P, a = 1.06853(12), b = 1.30740(16), c = 1.49546(17) nm, α = 101.791(2), β = 103.413(2), γ = 105.815(2)o, V = 1.8736(4) nm~3, M_r = 904.67, D_c = 1.604 g/cm~3, Z = 2, F(000) = 924, μ = 1.34 mm~(-1), GOOF = 1.049, the final R = 0.0324 and wR = 0.0797. The structure analysis shows that a chair-like structure [Cu_4O_4] is defined by three quadrilaterals shaped by four copper and four oxygen atoms, and every copper ion is coordinated by three oxygen atoms from three water molecules and two nitrogen atoms from one 1,10-phenanthroline molecule, giving a distorted square-pyramidal coordination geometry. The CV analysis results indicate that the electron transfer in the electrode reaction is quasi-reversible.

摘要：
The crystal structure of the title complex with the stoichiometric formula [Cu (PTA) (Phen)(2)](p-MBA) (H2O) (Phen=1,10-phenanthroline, PTA=terephthalic acid, p-MBA=p-toluic acid) has been determined by Single-crystal X-ray diffraction. The crystal (C,H,,C48H40CuN4O10, M-r=896.38) belongs to the monoclinic space group C2/c. with the following crystallographic parameters: a=1.778 6(3) nm., b=1.9125(3) nm, c=1.3899(2) nm, beta=114.686(2)degrees V= 4.2957(12) nm(3) D-c=1.386 g(.)cm(-3). Z=4, mu(Mo K alpha)=0.574 mm(-1), F(000)=1860, final GooF=1.019. R=0.054 0. wR= 0. 148 3 for 2 644 observed reflections (I > 2 sigma(I)). The crystal structure shows that the copper(II) ion is coordinated with two oxygen atoms from one terephthalic acid molecule and four nitrogen atoms from two 1,10-phenanthroline molecules, forming a distorted octahedral coordination geometry. The cyclic voltametric behavior of the complex is also reported.

A new cadmium complex Cd(α-FRA)_2(Phen)(H_2O) was synthesized by self- assembly reaction of α-furoic acid, phenanthroline (phen), and Cd(NO_3)_2(4H_2O. It crystallizes in monoclinic, space group P21/c, with a = 0.6799(2), b = 1.7780(6), c = 1.6866(6) nm, β = 94.912(6)o, V = 2.0315(12) nm~3, Dc = 1.742 g/cm~3, Z = 4, Mr = 532.77, μ(MoKα) = 1.124 mm_(-1), F(000) = 1064, R = 0.0411, wR = 0.0790. The structural analysis shows that the cadmium ion is coordinated with two nitrogen atoms from one phen molecule and four oxygen atoms respectively from two α-furoic acids and one water molecule, giving a distorted octahedral coordination geometry. The cyclic voltametric behavior of the complex was also discussed, which shows that the electrode process is irreversible in the electrode reactor.
