Synthesis and Crystal Structure of a New Complex [Cu（C_（14）H_9O_3）_2（C_5H_5N）_2（C_2H_5OH）_2]

The title compound of Cu(C14H9O3)2(C5H5N)2(C2H5OH)2(1) was synthesized via the hy- drothermal reaction of CuCl2·2H2O and 9-hydroxy-fluorene-9-carboxylic acid(HHF) with pyridine, and characterized by elemental analysis and infrared spectra. The crystal belongs to triclinic, space group P1 with a = 8.8302(12), b = 10.1625(14), c = 12.2708(17), α = 86.207(2), β = 69.562(2), γ = 64.932(2)o, V = 930.3(2) 3, Z = 1, Mr = 764.30, Dc = 1.364 g/cm3, F(000) = 399, S = 1.059 and μ(MoKα) = 0.644 mm-1. The final R = 0.0459 and wR = 0.1274 for 3414 observed reflections with I 2σ(I). The copper atom is six-coordinated by two oxygen atoms from two different 9-hydroxy-fluorene-9-carboxylate ligands, two pyridine nitrogen atoms and two ethanol oxygen atoms, forming a distorted octahedral coordination geometry. The extensive O–H···O hydrogen bonding connects the molecules to form a one-dimensional chain structure. Between adjacent one-dimensional chains, a two-dimensional layered structure was formed by fluorene ring π-π packing interaction. Between the layers, a three-dimensional structure was formed through the π-π packing interaction of the pyridine ring. Moreover, the thermal stability and photoluminescent property of the complex has been investigated.

A novel complex,[Mn(C_6H_(12)N_4)_2(H_2O)_4][Mn(H_2O)_6][SO_4]_2·6H_2O,was synthesized and hexagonal single crystals with centimeter-scale sizes were obtained by the method of solvent evaporation.It was characterized by elemental analysis,infrared spectrum,thermogravimetric analysis and X-ray single-crystal diffraction.The complex belongs to triclinic crystal system,space group P■ with a=9.3390(8),b=13.3520(13),c=16.3207(13)?,α=100.7160(3)°,β=90.1020(10)°,γ=109.9490(5)°,V=1874.9(3)?~3,Z=2,D_c=1.542 g/cm~3,M_r=870.64,μ=0.876 mm~(-1),T=293(2) K,F(000)=916 and S=0.990.The crystal structure determination displayed a distorted octahedral geometry around the manganese atom,which is bound to two nitrogen atoms from hexamethylenetetramine,acting as monodentate ligands,and to four aqua ligands.Variable-temperature magnetic measurements of the complex indicate the presence of weak antiferromagnetic interaction between manganese centers.

A new binuclear copper complex, [Cu2L2(pht)2]2·H2O(Hpht = 5,5-diphenylhydantoin, i.e. phenytoin; L = 2-diethylaminoethanol), has been synthesized by the solvothermal method, and characterized by elemental analysis, IR and single-crystal X-ray diffraction. The crystal belongs to the monoclinic system, space group C2/c with a = 31.918(3), b = 12.9222(15), c = 19.868(2) , β = 98.762(2)o, V = 8098.8(16) 3, Dc = 1.429 Mg/m3, Z = 4, F(000) = 3640, μ = 1.107 mm-1, R = 0.0560 and wR = 0.1276(I 2(I)). Each copper(Ⅱ) in a molecule is coordinated with N and O atoms from ligand L and N atom from ligand Hpht in a tetradentate manner. Moreover, two copper(Ⅱ) centers are bridged by two O atoms of hydroxyl groups from two L ligands to form a slightly distorted binuclear {Cu2O2} diamond configuration. In addition, the interaction of this complex with calf thymus DNA(CT-DNA) was investigated by UV-vis spectrum and viscometry, and the complex may bind to DNA through intercalation.
