A new Cu(II) complex, [CuL2(H2O)2]·H2O (HL = N-nicotinoylglycine), has been obtained using N-nicotinoylglycine, copper(II) acetate monohydrate and NaOH as raw materials. The structure of the Cu(II) complex was characterized by elemental analysis and single crystal X-ray diffraction analysis. The Cu(II) ion is six-coordinated with two N atoms from two pyridine groups of L ligand and four O atoms of four coordinated H2O molecules. The Cu(II) complex forms a 2D layered structure and 3D network structure by the interaction of O-H···O hydrogen bonds. The catalytic activities of the Cu(II) complex catalyst for benzyl alcohol oxidation were determined with molecular oxygen as oxidant.

A new binuclear Cu(II) complex, tetrakis-(μ2-acetato)-dihydrate-dicopper (II), has been prepared by the reaction of Cu(OAc)2·H2O with 2-formyl-benzenesulfonate-hydrazine in the CH3CH2OH/H2O (v : v = 1 : 1). It was characterized by elemental analysis, IR and X-ray single crystal diffraction analysis. The crystal of the Cu(II) complex belongs to monoclinic, space group C2/c with a = 13.162(3) Å, b = 8.5572(17) Å, c = 13.860(3) Å, β = 117.06(3) º, V = 1390.1(5) Å3, Z = 4, Dc = 1.889 μg·m-3, μ = 3.103 mm-1, F(000) = 792, and final R1 = 0.0548, wR2 = 0.1410. Two Cu(II) centers are bridged by oxygen atoms of carboxylato groups. Each Cu(II) center is five-coordinated with four O donor atoms of acetate and a O donor of coordinated water molecule. The molecules form three dimensional network structures by the inaction of π-π stacking and hydrogen bonds.

A novel dinuclear Tb(III) complex, [Tb(bpy)2L2] (bpy = 2,2’-bipyridine, H2L = homophthalic acid), has been synthesized and characterized by elemental analysis and single-crystal X-ray diffraction. The Tb(III) complex is monoclinic, space group P21/c with a = 9.368(2) Å, b = 15.948(4) Å, c = 12.216(3) Å, β = 103.023(4)º, V= 1778.2(7) Å3, Z = 2, Dc = 1.910 mg·m-3, μ = 4.011 mm-1, F(000) = 996, and final R1 = 0.0602, ωR2 = 0.2192. The result shows that the Tb(III) center is seven-coordination with a N2O5 distorted pengonal bipyramidal geometry. The luminescent property of Tb(III) complex was investigated.

A novel Zn(II) coordination polymer, [Zn(bpy)(acetato)2]n (bpy = 4,4’-bipyridine), has been synthesized and characterized by elemental analysis and single-crystal X-ray diffraction. The Zn(II) coordination polymer is triclinic, space group P-1 with a = 8.046(3) Å, b = 9.161(3) Å, c = 10.663(3) Å, α = 109.769(4)º, β = 99.966(5)º, γ = 101.666(5)º, V= 699.1(4) Å3, Z = 2, Dc = 1.614 mg·m-3, μ = 1.774 mm-1, F(000) = 348, and final R1 = 0.0541, ωR2 = 0.1605. X-ray diffraction analysis reveals that the Zn(II) center is six-coordination with a N2O4 distorted octahedral coordination environment. The Zn(II) complex forms 1D chain structure by the bridge of 4,4’-bipyridine and acetato.

A novel 1D chained Na(I) coordination polymer materials has been obtained by reaction of 2-hydrazinobenzoic acid with 2-formyl-benzenesulfonic acid sodium salt in CH3CH2OH/H2O. It was characterized X-ray single crystal diffraction analysis. The crystal of the Na(I) coordination polymer belongs to triclinic, space group P-1 with a = 6.0354(12) Å, b = 8.1922(16) Å, c = 18.729(4) Å, α = 93.70(3)º, β = 95.68(3)º, γ = 97.03(3)º, V = 911.8(3) Å3, Z = 2, Dc = 1.444 μg·m-3, μ= 0.245 mm-1, F(000)= 412, and final R1 = 0.0833, ωR2 = 0.2867. X-ray analysis reveals that each Na(I) center is six-coordination with a O6 distorted octahedron coordination environment. The Na(I) ions are linked through the O atoms of sodium 2-{(E)-[2-(2-carboxyphenyl) hydrazinylidene]methyl}benzenesulfonate to form 1D chain coordination polymer.
