5Syntheses 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 2005Rare Metals2005,24,4:1

7Synthesis 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 ) 1997Chinese Journal of Structural Chemistry1997,16,5:0
8Crystal 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) 1990Chemical Research in Chinese Universities1990,6,4:0
9Bibracchial 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) 1992Chemical Research in Chinese Universities1992,8,1:0
