摘要：
One binuclear sodium(I) complex [Na2(2-benzoylbenzoato)_4(Phen)_2(H_2O)_2]·H_2O has been synthesized with 2-benzoylbenzoic acid and 1,10-henanthroline as ligands. The crystal structure was determined by X-ray diffraction. The crystal belongs to the triclinic system with space group P1, a = 1.08096(8), b = 1.09619(8), c = 1.09740(8) nm, α = 79.0600(1), β = 71.0450(1), γ = 62.0540(1)o, V = 1.08533(1) nm~3, D_c = 1.421 g/cm~3, Z = 2, F(000) = 484, GOOF = 1.036, the final R = 0.0363 and wR = 0.0961. The crystal structure shows that two neighboring sodium(I) ions are linked together by two bridging water molecules, and each end position is coordinated with one 1,10-phenanthroline molecule and one 2-benzoylbenzoato to form a binuclear structure. Each sodium(I) ion in the molecule is coordinated with five atoms to give a distorted trigonal bipyramid. The fluorescence property of the title complex is also discussed.

摘要：
Anew copper(Ⅱ) complex {[Cu_2(Phen)_4(NO_3)][Cu(Phen)_2(L)]_2(L)_2(NO_3)_3}·2H_2O (1) with 2-benzoylbenzoic acid (HL) and 1,10-phenanthroline (Phen) as ligands has been synthesized. Crystal data for the complex are as follows: triclinic, space group P1, a=1.13857(5) nm, b=1.19349(7) nm, c=2.61531(13) nm, α=89.4280(10)°, β=82.753(2)°, γ=74.5370(10)°, V=3.3968(3) nm~3, Dc=1.408 g·cm~(-3), Z=1, μ(Mo Kα)=0.700 mm~(-1), F(000)=1480, final discrepancy factors R10.0571, wR_2=0.1334. In 1, there are two mononuclear cations [Cu(Phen)_2(L)]~+ and one dinuclear cation [Cu_2(Phen)_4(NO_3)]~(3+), and the four central Cu(Ⅱ) ions are all penta-coordinated. The electrochemical, fluorescent and magnetic properties of 1 were investigated. The results show that the electron transfer in the electrode reaction of 1 is quasi reversible, and the electrode reaction corresponds to Cu(Ⅱ)/Cu(Ⅰ). When the exciting radiation set at 488 nm, 1 can give off strong fluorescence band at around 494 nm. In addition, 1 displays diamagnetic property in temperatures range of 300~52 K. CCDC: 929034.

摘要：
A new Mn(II) complex [Mn(H2O)(L)(Phen)2].(H2O)3 (1) with 2,2′-bipyridine-3,3′-dicarboxylic acid (H2L) and 1, 10-Phenanthroline (Phen) as ligands has been synthesized. Crystal data for 1 are as follows: monoclinic, space group P21/c. In 1, the central Mn(II) ion is located in a distorted octahedral coordination environment. The magnetic, fluorescence and electrochemical properties of 1 are studied. The results show that 1 has weak antiferromagnetic property at low temperatures, and when the exciting radiation is set at 656 nm, 1 can give off one broad emission band at around 682 nm. The electron transfer is quasi reversible in the electrode reaction, corresponding to Mn(III)/Mn(II). CCDC: 874919.

摘要：
A dinuclear cobalt(Ⅱ) complex [Co_2(α-furacrylato)_4(Phen)_2(H_2O)].C_2H_5OH has been synthesized with a-furacrylic acid and 1,10-phenanthroline as the ligands, and its crystal structure was determined. The crystal is of monoclinic system, space group C2/c with a = 1.07388(8), β = 2.4300(2), c = 1.86708(14) nm, β = 104.3830(10)°, V = 4.719.4(7) nm~3, D_c = 1.503 g/cm~3, Z = 2, F(000) = 2196, GOOF = 1.053, the final R= 0.0343 and wR = 0.0883. The crystal structure shows that two neighboring cobalt(Ⅱ) ions are linked by the bridging coordination of two a-furacrylic acid anions and one water molecule, and their end positions are respectively coordinated with two 1,10-phenanthroline molecules and two α-furacrylic acid anions, forming a dinuclear structure. Both cobalt(II) ions adopt hexa-coordinated distorted octahedral geometry. The electrochemical and fluorescence properties of the title complex are also discussed.
