| 5 | Syntheses and crystal structures of rare earth (Nd, Gd) 1-D chain com-plexes with N-p-tolylsulfonyl-β-alanine显示文摘Two rare earth complexes of Ts-β-AlaH with the formula of [Ln2(H2O)4(Ts-β-AlaH)6]n·4nH2O (where Ln = Nd(1), Gd(2); Ts-β-AlaH = N-p-tolylsulfonyl-β-Alanine) have been synthesized and characterized by elemental analysis, IR, and X-ray diffraction. The results show that the two complexes are isostructural. They crystallize in a monoclinic system with P21/n space group. Crystal data for 1: a = 0.95149(19) nm, b = 1.9012(4) nm, c = 2.2863(5) nm, β = 100.37(3)°, Z = 4, Dc = 1.509 mg/cm3, F(000) = 1880, R1 = 0.0560, wR2 = 0.1564 [I > 2σ (I)]; for 2: a = 0.9495(2) nm, b = 1.9037(4) nm, c = 2.2987(5) nm, β = 99.87(3)°, Z = 4, Dc= 1.541 mg/cm3, F(000) = 1916, R1 = 0.0515, wR2 = 0.1566 [I>2σ (I)]. The two complexes are one-dimensional chains and the coordination number of the Nd3+ or Gd 3+ ion is nine. | MA Lufang LI Xiaodong WANG Liya LIANG Fupei ZHANG Manbo YU Kaibei | 2005 | Rare Metals2005,24,4: | 1 |

| 7 | Synthesis and Crystal Structure of Dinuclear Copper(Ⅱ)Complex Cu_2(μ-PhCOO)_4(amet)_2·2CH_3COCH_3显示文摘Reaction of copper powder, dibenzoyl peroxide and 2-amino-4methyl-5-ethoxycarbonyl thiazole (amet) by refluxing in acetone yielded the dinuclearcopper(Ⅱ) complex Cu2 (μ-PhCOO)4 (amet)2- 2CH3COCH3. Crystal structure determination showed that each copper atom is coordinated by four bridged benzoxy and oneamet molecule with an M-M bond (Cu-Cu (A) = 2.6899 (7 ) ), therefore the coor-dination environment around the copper center is a distorted square pyramid with N(1)at the apical position. Blocks of Cu2 (μ-PhCOO)4 (amet)2·2CH3COCH3 crystallize inthe triclinic space group Ph, with Mr= 1100.14, a= 9. 631 (1), b=10. 446 (2), c=12. 758(2) ; a=91. 31 (1), β=95. 50(1),γ= 94. 87(1)°, V=1272. 4(3), Z=1, Dc= 1. 436 g/cm3, F(000) = 570, μ=0. 986 mm-1 and R=0.033, Rw=0.049.The IR spectra, which are of great interest since the molecule has ketone, ester andcarboxylate group simultaneously, are also discussed. | GUO Sheng-Li ZHAO Zhuan-Yun WANG Guo-Jun YIN Yuan-Qi(Lanzhou Institute of Chemical Physics, the Chinese Academy of Scicnces, Lanzhou 730000)YU KAIBEI(Chengdu Institute of Organic Chemistry, the Chinese Academy of Sciences, Chengdu 610041 ) | 1997 | Chinese Journal of Structural Chemistry1997,16,5: | 0 |
| 8 | Crystal and Molecular Structure of Copper (Ⅱ) Dimeric Complex of S-Methyl-β-N-(Pyridine N-Oxide-2-ylmethylidene) Dithiocarbazate with Acetonitrile显示文摘The crystal and molecular structure of copper(Ⅱ) dimeric complex of S-methyl-B-N-(pyridine N-oxide-2-ylmethylidene) dithiocarbazate with acetonitrile, [CuL (CH3CN)]2 (ClO4)2, was determined by X-ray diffraction. The complex crystalizes in monoclinic system with space group P21/n, a= 7. 685(2), 6=20.160(6), c= 10. 847(5) A ,B = 107.89(3), Z=2,Dc=1.788 g/cm3, F(000) = 835. 8, u= 18. 17 cm-1(Moka,R= 0. 057.Each Cu(Ⅱ) ion in the complex is surrounded by a distorted square pyramidal. The basal plane is comprised of S, N and O atoms of one ligand together with a N atom of the solvent--acetonitrile, while the axial position is occupied by the S atom of the other ligand. The bond length of Cu-S(bridging) is 3. 038A . and Cu-Cu distance is 3. 700A. | Yu Kaibei and Zhou Zhongyuan (Chengdu Center of Analysis and Determination, Academia Sinica, Chengdu)Gou Shaohua, You Xiaozeng and Xu Zheng (Coordination Chemistry Institute, Nanjing University, Nanjing) | 1990 | Chemical Research in Chinese Universities1990,6,4: | 0 |
| 9 | Bibracchial Lariat Ethers(Ⅰ)——The Synthesis and Crystal Structure of the N,N'-bis(2-Methoxy-1-Naphthylmethyl)-4,13-Diaza-18-Crown-6 Sodium Iodide Complex显示文摘Diaza Crown ethers are versatile complexing reagents, their complexing abilities are dramatically modified by the electron donating atoms on substituents attached to the nitrogen if they can give a three-dimensional cavity as in cryptates. Hence the synthesis and characterization of bibracchial lariat ethers (BIBLES) have received much attention. In the preparation of new BIBLES, a complex Ⅱ was unexpectedly obtained. | Ge Yuhua, Wang Defen and Hu Hongweng (Department of Chemistry, Nanjing University, Nanjing)Zhou Zhongyuan and Yu Kaibei (Chengdu Center of Analysis and Determination, Academic Sinica, Chengdu) | 1992 | Chemical Research in Chinese Universities1992,8,1: | 0 |
