摘要:
A novel one-dimensional chain copper(II) coordination polymer {[Cu(2,2′-bipy)-(HPDA)](HPDA)(H2O)}n has been hydrothermally synthesized using pimelic acid, 2,2′-bipyridine and copper perchlorate in the mixture of water and methanol. The crystal structure was determined as a monoclinic system, space group P21/c, with a = 1.01139(14), b = 2.6898(4), c = 1.02105(14),β = 109.651(2)°, V= 2.6159(6) nm3, Dc = 1.412 g/cm3, Z = 2, F(000) = 1164, GOOF = 1.044, R = 0.0570 and wR = 0.1448. The copper ion is coordinated with two nitrogen atoms of one 2,2′-bipyridine molecule and three oxygen atoms from two heptane diacid molecules, forming a distorted square-pyramidal geometry. The result of TG analysis shows that the title complex is stable under 200.0 °C.

A novel one-dimensional chain coordination polymer [Mn(NAA)_2(4,4'-bipy)(H_2O)_4]n has been synthesized with α-naphthaleneacetic acid, 4,4?-bipy and manganese(II) sulfate as raw materials. Crystal data for this complex: monoclinic, space group P2_1/c, a = 1.1421(2), b = 1.6337(3), c = 0.94177(19) nm, β = 112.15(3)o, V = 1.6275(6) nm~3, D_c = 1.407 g/cm~3, Z = 2, μ(MoKα) = 0.467 mm-1, F(000) = 722, S = 1.007, R = 0.0412 and wR = 0.1022. The crystal structure shows that two neighboring manganese(II) ions are linked together by one 4,4?-bipy molecule, and the whole complex molecule forms a one-dimensional chain structure. Each manganese(II) ion is coordinated with two oxygen atoms of two α-naphthaleneacetic acid molecules, two nitrogen atoms of two4,4'-bipy molecules and two oxygen atoms from two water molecules, giving a distorted octahedral coordination geometry. The electrochemical properties were also analyzed.

A one-dimensional chain coordination polymer [Cu(phen)(2,4,6-TMBA)(2)(H2O)](n) has been synthesized by reacting 2,4,6-trimethyl-benzoic acid, 1,10-phenanthroline and Cu(II) perchlorate and its structure was characterized. Crystal data for this complex: tetragonal, space group 14(1), a = 2.0293(3), b = 2.0293(3), c = 1.3758(2) nm, alpha = beta = gamma = 90 degrees, V = 5.6657(13) nm(3), D-c= 1.379 g/cm(3), Z = 8, mu(MoK alpha) = 0.815 mm(-1), M-r = 588.14, F(000) = 2456, S = 1.047, R = 0.0459 and wR = 0.1053. The crystal structure shows that two neighboring Cu(II) ions are linked together by one bridging-chelating 2,4,6-trimethyl-benzoic group, forming a one-dimensional chain structure. Each Cu(II) ion is coordinated with two nitrogen atoms from one 1,10-phenanthroline molecule, three oxygen atoms from three 2,4,6-trimethyl-benzoic acid molecules and one oxygen atom from one water molecule, giving a six-coordinate distorted octahedral coordination geometry. The cyclic voltammetry behavior of the complex was also investigated.

A new cadmium complex [Cd(phen)3]-(ClO4) 2-(α-FRA)(H2O)3 was prepared by self-assembly of α-furoic acid, 1,10-phenanthroline (phen), and cadmium perchlorate.

The crystal structure analysis indicates that the cadmium ion is coordinated with six nitrogen atoms from six 1, 10-phenanthroline molecules, giving a distorted octahedral coordination geometry. The cyclic voltametric behavior of the complex was also investigated.

One novel complex [Ni(phen)_3]·(C_8H_(12)O_4)·(H_2O)_(14) with hexane dicarboxylic acid and 1,10-phenanthroline has been hydrothermally synthesized and characterized. Crystal data: monoclinic, space group C2/c, a = 2.3475(5), b = 1.2208(2), c = 1.9499(4) nm, β = 114.682(3)°, V = 5.0778(16) nm~3, D_c = 1.339 g/cm~3, Z = 4, μ(MoKα) = 0.458 mm~(–1), F(000) = 2168, GOOF = 1.014, R = 0.0401 and w_R = 0.0961. The nickel(II) center in the title complex is coordinated with six nitrogen atoms of three 1,10-phenanthroline molecules, giving a distorted octahedral coordination geometry. However, the nickel(II) ion does not coordinate to the hexane dicarboxylic acid. The complex molecules form a 3D structure through hydrogen bonds. TG analysis shows that the title complex is stable below 240.0 ℃.
