摘要：
One new cadmium complex [Cd(phen)3]·(ClO 4)2·(p-MBA)2·(H 2O)2 has been hydrothermally synthesized by reacting p-methylbenzoic acid (p-MBA), 1,10-phenanthroline (phen) and cadmium perchlorate. It crystallizes in the triclinic system, space group P1̄, with a = 1.2809(3), b = 1.3431(3), c = 1.3734(3) nm, α = 84.259(4), β = 71.603(3), γ = 74.424(3)°, V = 2.1594(8) nm3, Dc = 1.532 g/cm3, Z = 2, F(000) = 1008, μ = 0.697 mm-1, R = 0.0646 and wR = 0.1648. The crystal structure shows that the cadmium ion is coordinated with six nitrogen atoms from three 1,10-phenanthroline molecules, forming a distorted octahedral coordination geometry. The result of electrochemical property analysis shows that the electron transfer in the electrode reaction is irreversible.

One novel complex Mn2(phen)2(p-CBA) 4(H2O) has been hydrothermally synthesized from p-chlorobenzoic acid (p-CBA), 1,10-phenanthroline (phen) and anhydrous manganese(II) sulfate and then characterized. Crystal data for this complex: monoclinic, space group C2/c, with a = 2.3416(3), b = 1.5604(2), c =1.5605(2) nm, β = 121.048(2)°, V= 4.8849(12) nm3, Dc = 1.510 g/cm3, Mr = 555.26, Z = 8, μ = 0.798 mm -1, F(000) = 2256, GOOF = 1.032, the final R = 0.0393 and wR = 0.0816. The crystal structure shows that two neighboring manganese(II) ions are linked together by two bridge-chelating p-chlorobenzoic groups and one bridging water molecule, forming a cage structure with the Mn-Mn bond distance of 0.3512 nm. Each manganese(II) ion is coordinated by two nitrogen atoms of one 1,10-phenanthroline molecule and four oxygen atoms from three p-chlorobenzoic acid anions and one water molecule, giving a distorted octahedral coordination geometry. The cyclic voltammetric behavior of the complex was also investigated.

The title complex (C26H18CuN2O 6, Mr = 517.96) has been synthesized by the reaction of a-furanacrylic acid with 1,10-phenanthroline (phen) in the solvent mixture of water and methanol. Crystal data: monoclinic, space group C2/c with a = 2.2927(4), b = 1.01248(18), c = 1.05061(18) nm, β= 111.188(3)°, V = 2.274(7) nm3, Dc = 1.513 g/cm3, Z = A, F(000) = 1060, μ = 1.007mm-1, R = 0.0320 and wR = 0.0781. The crystal structural analysis shows that the copper atom is coordinated with four oxygen atoms from two α-furacrylic acids and two nitrogen atoms from 1,10-phenanthroline, giving a distorted octahedral coordination geometry. The result of electrochemical analysis shows that the electron transfer in the electrode reaction is quasi-reversible.

Each cobalt(II) ion is coordinated with two nitrogen atoms from two 4,4′-bipy molecules and four oxygen atoms from four water molecules, giving a distorted octahedral coordination geometry.

The structural determination shows that the copper atom is coordinated by three oxygen atoms from two o-methylbenzoic acids and one water molecule together with two nitrogen atoms from 2,2'-bipyridine, giving a distorted square-pyramidal coordination geometry.The cyclic voltammetric behavior of the complex is also discussed.
摘要：
Based on hydrophobic and electrostatic interactions, a norfloxacin (NOF) imprinted polymer (PI) was prepared by the combined use of bismethacryloyl-beta-cyclodextrin (BMA-beta-CD) and 2-(diethylamino)ethylmethacrylate (DEAEM) as functional monomers. Compared with the molecularly imprinted polymers (MIPs) using only BMA-P-CD or DEAEM as a functional monomer, P-2 and P-3, respectively, P, showed higher binding affinity and specificity for NOF in aqueous media. Scatchard plot analysis revealed that two classes of binding sites were formed in the imprinted polymer with dissociation constants of 0.32 mu mol/ml and 1.19 mu mol/ml, respectively. It demonstrated that the combination of hydrophobic effect and electrostatic interaction in molecular imprinting was essential for the improvement of the selective ability of the imprinted polymer. Factors that influenced rebinding of the imprinted polymer including pH, water content in the adsorbed solution were explored. (C) 2007 Elsevier B.V. All rights reserved.
