Crystal structure of copper (II) complex with a new aminocarboxylate ligand, 3-hydroxyl-1, 5-diazacycloheptane-N,N-diacetate, C9H14CuN2O5.H2O, Mr=311.78 is reported. It crystallizes in orthorhombic Pna21 with a=13.340(4), b=8.127(1), c=10.583(4) , V=1147.2(7)3 , Z=4, Dc=1.805g/cm3, μ=19.287cm-1 (MoKα), F(000)=644. The final R and Rw are 0.049 and 0.065 for 888 observed reflections with I≥3σ(I). The result of X-ray structure determination shows that the Cu(Ⅱ) forms a planar complex with two oxygen atoms and two nitrogen atoms of the ligand. 相似文献

Two supramolecular complexes [Zn(tacd)2](C6H8O4)·6H2O(1) and [Cu(tacd)2]Cl2·4H2O(2) were synthesized and characterized by elemental analysis, IR spectra, TGA and single-crystal X-ray diffraction analysis. The crystal structure showed that the metal ions in complexes 1 and 2 had similar coordination circumstance. But for the complex 2, it formed a novel two-dimensional supramolecular network with 12-membered rings and four-membered rings via hydrogen bond interaction. The thermal gravimetric analyses indicated that the two complexes had similar steps of weight-loss. On the basis of experiment, the two complexes were calculated by DFT-B3LYP/6-31G(d) in Gaussian 03. The results of calculation are in good agreement with the experiment. 相似文献

1 INTRODUCTION Benzoic acids with substituent of amino are a class of rigid ligands possessing several functional groups. When they coordinate to metal ions, versa- tile coordination modes will be presented with pre- sence of not only coordinate-covalent bonds but also hydrogen bonds. Besides, diverse coordination modes of carboxyl and rigid frame of benzene ring gua- rantee the stability of multi-dimensional structures of the synthesized metal complexes. Thus ligands of this class are o… 相似文献

Homobinuclear complex (HCuL)2 (1) (H3L: N-3-carboxylsalicylidene-N'-salicylaldehyde-1,2-diaminoethane) was obtained from self-organization of the reported complex HCuL, and its crystal structure was determined through X-ray diffraction at room temperature. The crystal of complex 1 belongs to monolinic system, the space group Cc, a=2.5326(5) nm, b=0.88861(18) nm, c=1.3738(3) nm, β=96.95(3)°, Z=4, R1=0.0520, wR2=0.1185. (HCuL)2 is a dimeric molecule and has extended phenolic oxygen-bridged structure. In addition, using mononuclear complex HCuL as building blocks, Cu(Ⅱ)-Mg(Ⅱ)-Cu(Ⅱ) heterotrinuclear complex 2 was synthesized, and its crystal structure also has been determined by X-ray analysis. The crystal of complex 2 is of monoclinic system, space group Pc, a=1.1816(2) nm, b=1.5599(3) nm, c=1.9642 (4) nm, β=98.22°, Z=2, R1=0.0701, wR2=0.1498. Each dissymmetricai cell unit of complex 2 contains two heterotrinucler neutral molecules: {[CuL(H2O)]Mg[CuL(CH3OH)]} and {[CuL]Mg[CuL(H2O)]}. 相似文献

Three palladium (II) complexes with the isonitrosobenzoylacetoneimine (HIBI) ligand, Pd (p‐CH3C6H4IBI)2 (1), Pd (C6H5IBI)2 (2) and Pd2Cl2 (C6H5CH2IBI)2 · CHCl3 (3), were prepared and characterized by IR, Raman and X‐ray diffraction studies. The geometries around the palladium atoms in the complexes 1 and 2 are distorted trans‐PdN4 square planes, and the Schiff base ligands RIBI? are coordinated through their oximo‐nitrogen atoms and imino‐nitrogen atoms. The week Pd…H? C agostic interactions [Pd…H = 0.2764 nm] complete the hexacoordinate environment around palladium in the complex 1. The octahedral deformation of the classical square planar environment of the Pd atom is due to the week Pd…O (1b) interactions [Pd? O (1b) = 0.3157 (9) nm] in the complex 2. The complex 3 is a first example of binuclear complex with isonitrosoketoimine ligands, in which one of oximo groups is coordinated through oximo‐nitrogen and oximo‐oxygen atoms. 相似文献

A New Dinuclear Cu(Ⅱ) Complex of a Ligand with Benzimidazole Group - Synthesis and Crystal Structure
LI Qing-Xiang WANG Xiu-Feng YANG Xiang-Liang XU Hui-Bi 《结构化学》2007,26(6):707-710
A new dinuclear copper complex, [Cu(C9H11N3)Cl2]2(C18H22Cl4Cu2N6), has been synthesized and characterized by X-ray structure determination. It crystallizes in the triclinic P1^- space group with a = 7.526(3), b = 9.473(4), c = 9.535(3)A, α = 117.214(10), β = 108.251(9), γ = 91.560(6)°, V = 562.3(4)A^3, Z = 1, Mr = 591.30, F(000) = 298, Dc = 1.746 g/cm^3, μ(MoKα) = 2.385 mm^-1, the final R = 0.0577 and wR = 0.1248 for 2188 unique reflections with 1629 observed ones (Ⅰ〉 2σ(Ⅰ)). In the title complex, each copper(Ⅱ) atom is located at the center of a distorted trigonal bipyramid of five coordination atoms (two nitrogen and three chlorine atoms). Two copper(Ⅱ) atoms were bridged by two chlorine anions (Cl(2) and Cl(2a)) to form a Cu(Ⅱ)-Cu(Ⅱ) binuclear entity with the distance between two copper(Ⅱ) atoms of 3.398 (A). 相似文献
