<正> The title complex has been synthesized and characterized by elementary analysis,FT-IR and Raman spectra. The crystal and molecular structure was determined by X-ray diffraction analysis. The crystal of this complex C6H18O12P3Eu(Mr = 527. 08) is monoclinic with space group P21/c and cell parameters a= 10. 418(2) ,b= 16. 596(6) ,c =10. 766(2) A ,β=111. 67(2)°,V=1729. 8(8) A3 and Z=4. Dimethyl phosphate an-ions coordinate with europium ions through double O-P-O bridges to form a special network of rings-linking-rings. The local coordination geometry of Eu is a slightly distorted octahedron.  相似文献

The Co(II) ion is in a distorted centrosymmetric six-coordinate octahedral environment with two Ntriazole, two Omethanol and two Cl atoms. Via hydrogen bonds the configuration of 1 has been extended into 1D chains which are developed to 2D layers via π-π sticking action, and these layers are further extended into a 3D network by hydrogen bonds. The antibacterial activity of the title compound has been detected, and the results show that the ligands and cobalt(II) complex exhibit certain fungicidal activity against several bacteria. Furthermore, the spectral properties of the title compound have been also studied and discussed.  相似文献

One dinuclear manganese(II)complex [Mn2(C12H8N2)4(C8H5O4)2](C8H4O4)·H2O has been synthesized with o-phthalic acid and 1,10-phenanthroline.The crystal structure was determined by X-ray diffraction.The crystal belongs to the triclinic system,space group P1 with a = 1.17767(3),b = 1.22292(2),c = 1.35860(3)nm,α = 110.5300(10),β = 97.6140(10),γ = 93.7300(10)o,V = 1.80307(7)nm3,Dc = 1.404 g/cm3,Z = 2,F(000)= 784,the final GOOF = 1.047,R = 0.0398 and wR = 0.1038.The crystal structure of the title complex consists of one [Mn2(C12H8N2)4(C8H5O4)2]2+ cation,one uncoordinate o-phthalate anion(C8H4O4)2-and one uncoordinate water molecule.In [Mn2(C12H8N2)4(C8H5O4)2]2+,the central Mn(II)ion is coordinated by four nitrogen atoms and two oxygen atoms to give a distorted octahedral coordination geometry.The electrochemical property of the title complex was also studied.  相似文献

The polyoxoanion incorporated {Mn(CO)3^+} complex, (n-Bu4N)2[Mo6O16(OCH3)2{HOCH2C(CH2O)3}2·{Mn(CO)3}2](1), has been synthesized by the reaction of (n-Bu4N)4[Mo8O26] with Mn(CO)5Br in methanol, in the presence of C(CH2OH)4. The complex 1 has been characterized by IR, UV-Vis, X-ray single crystal diffraction, and TG. Crystal data for the complex 1:C25H48MnMo3NO16 (1), Triclinic Pi, a=0.9405(3) nm, b=1.3351(4) nm, c=1.5455(4) nm, α=103.206(5)°, β=102.165(5)°, γ=100.784(5)°, V=1.7896(9) nm^3, Z=2, R1=0.0703, wR2= 0.1495. The structure analysis of complex 1 shows that the complex consists of two tetrabutylammonium cations and a polyoxomolybdate anion that incorporates two fac-Mn(CO)3^+ units. The anion of complex 1 can be considered as the dimer of two rhomb-like anions by sharing of two comers.  相似文献

The title complex [NH_3CH_2CH(NH_2)CH_3]_2 [M(Ⅵ)O_2(OC_6H_4O)_2](M= Mo_(0.6)W_(0.4))was synthesized via a simple solution-phase chemical route.The determination of single crystal X-ray diffraction revealed that the title compound is crystallized in a monoclinic system with P2(1)/n space group,a=1.0913(10)nm,b=1.0442(10)nm,c=1.8842(19)nm,α=90°,β=96.530(17)°,γ=90°,Z=4,and V=2.133(4)nm3.The mononuclear anionic unit [M(Ⅵ)O2(OC6H4O)2]2-displays chiral pseudo-octahedral [MO_6] coordination geometry and is linked by chiral cations via hydrogen bond and π…π stacking interaction.The transmission electron microscopy images show that the title complex is comprised of nano-particles with diameters ranging from 20 to 50 nm.The NMR study shows the 1H downfield chemical shifts of [NH_3CHaHbCH(NH_2)CH_3] cations in the title complex when it is mixed with adenosine-triphosphate(ATP),and the chemical shift difference between Ha and Hb is increased greatly,and most of the catecholate ligands dissociate from the central metal atoms.The DNA cleavage activity experiment reveals that DNA cleavage promoted by the title complex is lower than that by Na_2MoO_4 which possesses antitumor pro-perty,but higher than that by Na_2WO_4.  相似文献

A novel imide nickel complex [Ni(CH3CONCOCH3)2·2(H2O)] was synthesized by the solvothermal reaction of nickel acetate tetrahydrate and acetonitrile.What amazed us is that acetonitrile had changed into acetyl imide in enol form during the formation process of the title complex.The complex was characterized by elemental analysis,IR spectrum and X-ray single-crystal diffraction analysis.It crystallizes in the orthorhombic system,space group Pbca with a = 7.4503(7),b = 13.1089(12),c = 14.1303(14),V = 1380.0(2)3,Dc = 1.420 g/cm3,Mr = 294.94,Z = 4,F(000) = 616,μ = 1.422 mm-1,the final R = 0.0487 and wR = 0.1482.The four-coordinated nickel(II) center is surrounded by 4O atoms from two imide ligands and has a distorted square planar geometry.The complex is connected to form a supramolecule with an infinite three-dimensional network through intramolecular and intermolecular hydrogen bonds.Antimicrobial activity was investigated by agar diffusion method,and the result showed that the complex was active against coli bacillus,staphylococcus aureus and bacillus subtilis.The thermal stability of the title complex was also studied by TG-DTA method.  相似文献

A novel 2D Mn(Ⅱ) coordination polymer [Mn(CH3COO)2(INH)]n(INH=isoniazid) has been synthesized in DMF solution with isoniazid and Mn(CH3COO)2 . The polymer was characterized by single-crystal X-ray diffraction analysis, FTIR and X-ray powder diffraction (XRPD). The crystal belongs to the monoclinic system, space group P2 1 /c with a=9.3251(18), b=16.340(3), c=8.8096(17) , β=94.747(3)°, V=1337.7(4) 3 , Z=4, μ(MoKα)=1.006 mm -1 , F(000)=636, R=0.0754 and wR=0.1375 (I > 2σ(I)). In the complex, each Mn(Ⅱ) atom is coordinated to three CH3COO- groups and two INH ligands. The Mn(Ⅱ) atoms locate in a distorted coordination octahedron and are bridged by CH3COO- ions to form a 1D S shaped chain extending along the c direction. The INH molecules act as bridges to link the Mn(Ⅱ) atoms of adjacent chains and further construct a lamellar polymer. The remaining coordination site is occupied by an O atom of the other CH3COO-. The experimental results show that the title complex has good luminescence property and could be used as potential optical materials.  相似文献

For (NH3CH2CH2NH3)2Bi2I10 2, it crystallizes in monoclinic, space group P21/n with Mr= 1811.20, a = 8.434(4), b = 13.862(6), c = 13.362(6)A, V = 1499.9(12)A^3, Z = 2, Dc = 4.010 g/cm^3, F(000) = 1536,μ(MoKα) = 22.007 mm^-1, T = 293(2) K, the final R = 0.0584 and wR = 0.1451 for 1798 observed reflections with I 〉 2σ(I). The structures of 1 and 2 contain halobismuthate monomer and dimers, respectively. It is noteworthy that the dimers and their organic counters in 2 connect each other by N…I hydrogen bonds to form a layered structure, and the electrostatic interactions and crystal packing forces between layers give rise to the packing of the crystal. The optical absorption spectra of 1 and 2 reveal the appearance of sharp optical gaps of 2.13 and 2.01 eV, respectively.  相似文献

A new luminescent Cd(Ⅱ) compound, [Cd3(OABDC)2(bipy)2(H2O)2]n (1, H3OABDC = 5-oxyacetateisophthalic acid, bipy = 4,4'-bipyridine), has been prepared by the assembly of Cd(Ⅱ) salt with the mixed ligands of H3OABDC and 4,4'-bipy under hydrothermal conditions. The crystal structure is of monoclinic, space group P2/n with a = 13.6730(5), b = 10.1265(3), c = 15.9752(4) , β = 103.061(3)o, V = 2154.70(11) 3, C40H34Cd3N4O18, Mr = 1195.94, Z = 2, Dc = 1.843 g/cm3, F(000) = 1180, μ = 1.549 mm-1, the final R = 0.0409 and wR = 0.1291 for 2746 observed reflections (I > 2σ(I)). Single-crystal X-ray structural analysis reveals that compound 1 features a self-penetrating two-dimensional (2D) layered structure. According to topology analysis, this 2D framework can be characterized as a (3,4)-connected (6.72)2 (62.8)2 (73.8.102) net that has never been reported before. Finally, these 2D layers are further linked by intermolecular hydrogen bonds and π…π interactions to form a three-dimensional (3D) supramolecular framework. Moreover, Compound 1 exhibits strong blue photoluminescence at room temperature.  相似文献
