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.
摘要:
A novel manganese coordination polymer [Mn(L)_2(bipy)]_n (HL = 3,5-dimethylbenzoic acid, 4,4'-bipy = 4,4'-bipyridine) has been synthesized by a hydrothermal method. The molecular and crystal structures were determined by single-crystal X-ray diffraction. The crystal is of monoclinic, space group C2/c with a = 2.0996(8), b = 1.1835(5), c = 0.9958(4) nm, β = 110.161(5)°, V = 2.3229(16) nm~3, Z = 4, C_(28)H_(26)MnN_2O_4, Mr = 509.45, Dc= 1.457 g/cm~3,μ = 0.607mm~(-1), F(000) = 1060, Rint= 0.0566, R = 0.0334 and wR = 0.1078. In the crystal the manganese atom is six-coordinated by two nitrogen atoms from 4,4'-bipy and four oxygen atoms from 3,5-dimethylbenzolate molecules, completing an octahedral geometry. The 4,4'-bipy molecules bridge the infinite chain [Mn(L)_2(bipy)]_n to form a two-dimensional layer.

摘要:
A series of metoclopramide (MCP)-imprinted polymers utilizing methacrylic acid or 2-vinylprindine (2-VP) as functional monomer and chloroform, acetonitrile or methanol as porogen were prepared. The affinity and specificity of these polymers were evaluated by equilibrium binding experiments. Proton NMR model studies on interactions between the template and functional monomer analogues, acetic acid and d(5)-pyridine, were performed in the same solvents that were used as porogens for the molecularly imprinted polymers (MIPs). A correlation was found to exist between the binding strength and specificity of a particular polymer and the extent of monomer-template interactions shown by the corresponding NMR spectrum. So, a useful means is provided to predict the performance of a MIP in this paper. Based on the results of NMR experiments and selectivity experiments, the role of functional groups of the template in the formation of complementary interacting sites in the polymer in different porogens was discussed, and the mechanism of molecular recognition of the MIPs was proposed.

摘要:
A mononuclear manganese complex [Mn(2,2′-bipy)(H20) 4]·(m-phth) (2,2′-bipy=2,2′-bipyridine, m-phth=isophthalate) has been synthesized by hydrothermal methods. The crystal structure was determined by single-crystal X-ray diffraction. The crystal is of orthorhombic, space group Pnna with a=0.766 8(8) nm, b=2.050 2(2) nm, c=1.247 0(13) nm, V=1.960 4(4) nm3, Z=4, Mr=447.30, D c=1.376 g·cm-3, μ=0.722 mm-1, F(000)=924, Rint= 0.027 0, R=0.028 0 and wR=0.075 5. In the crystal the manganese atom is six-coordinated by two nitrogen atoms from 2,2′-bipyradine and four oxygen atoms from water molecules, completing an octahedral coordination geometry. The isophthalate molecules are included in the lattice and connected to Mn (2,2′-bipy)(H2O)4 by hydrogen bonding interactions to form a three-dimensional supramolecular structure.
