Synthesis and Structure Characterization of Aqua-（μ2-carbonato-O,O′）-（2,2′-bipyridyl）-copper（Ⅱ） Dihydrate

Under hydrothermal conditions the reaction of cis-aconitic acid with Cu2(OH)2CO3 and bipy (bipy = 2,2'-bipy) in H2O/DMF (3:2) afforded a neutral mononuclear compound [Cu- (bipy)((2-CO3)(H2O)](2H2O, which has been structurally characterized by single-crystal X-ray diffraction analysis. The crystal belongs to triclinic, space group Pī with a = 8.3950(5), b = 8.7974(5), c = 9.4496(3)（A。）, α = 98.270(3), β = 93.014(3), γ = 100.068(3)°, V = 677.83(6) （A。）3, Dc = 1.635 g/cm3, Z = 2, C11H14CuN2O6, Mr = 333.78, μ = 1.637 mm－1, λ(MoKα) = 0.71073 （A。）, F(000) = 342, the final R = 0.0616 and wR = 0.1273 for 1621 observed reflections with I > 2σ(I). The structure of the complex contains a distorted square pyramidal core with a bipy, a carbonate anion and a water molecule coordinating to a CuⅡ atom. The dihedral angle between the two planes composed of N(1)N(2)Cu(1) and O(1)O(3)Cu(1) is 21.73(8)°. The intermolecular hydrogen bonds (O…O) are observed in the crystal structure.     

Synthesis and Crystal Structure of Zn（Ⅱ） Complex with 2-Aminopyridine and Acetylacetone

1 INTRODUCTION As one kind of compound with extensive phy- siological and pharmacology activities[1], 2-amino- pyridine is easy to form complexes, and some of which may catalyse hydrolysis of ester[2]. Acetyl- acetone is an useful intermediate in the synthesis of sulfanilamide, additive and catalyst[3]. Complexes containing acetylacetone take on excellent lumines- cent properties[4]. To be an active center of some sig- nificant enzymes[5, 6], zinc takes the form of its su- pramolecular co…     

Synthesis,Characterization and Crystal Structure of （2,2′—Bipyridine）（μ—maleato）copper（Ⅱ）Dihydrate

The title polymeric complex [Cu(C₄H₂O₄)(C₁₀H₈N₂)]_n·2nH₂O was prepared and its crystal structure was determined by X‐ray diffraction methods. The crystal belongs to space group P2₁/c with cell dimensions of a = 1.0104(1), b = 1.9952(2), c = 0.7357(2) nm, β= 98.38(2)° and Z = 4. The complex forms zig‐zag chains along crystallographic axis c via Cu—O (carboxyl) bond in the apical direction. Each repeated unit consists of a square pyramidal Cu(II) centre with one maleate dianion and one 2,2′‐bipyridine forming a basal plane. Adjacent chains link to each other by H‐bonding between carboxyl groups and crystalline water. The distance of 0.3482 nm between parallel bipyridine rings shows a π‐π stacking interaction. The title complex was also characterized by IR, UV and ESR spectra.     

Synthesis and Crystal Structure of Dichlorodianiline Palladium （Ⅱ） （C6H5NH2）2PdCl2

1 INTRODUCTION Palladium compounds have attracted much attention as a consequence of their application in homogeneous and heterogeneous catalyses[1]. For instance, palladium compounds are the most active catalysts for the carbonylation, such as palladium-catalyzed carbonylation of nitroarenes, aryl halides, alkyne and so on[2～4]. Some dramatic results in the homogeneous catalysis of the reactions of organic compounds, particularly the successful commercial exploitation of the Wacker on…

Synthesis and Crystal Structure of a Novel Two-dimensional Supramolecular Complex Ni（C6H7N）2（SCN）2（H2O）2

1 INTRODUCTION Supramolecular chemistry is based on the notion of creating novel structural and functional extended systems using noncovalent interactions between prefabricated molecular or ionic building blocks[1]. More recently, the design of supramolecular architec- tures by self-assembly of small building blocks has become a major research area[2, 3] due to their poten- tial applications in many fields such as selective clathration[4, 5], molecular recognition[6, 7], catalysis[8, 9] a…     

Synthesis and Structure of a New Dimanganese Complex [Mn2（μ-OAc）2（phen）4]（ClO4）2

1INTRODUCTION Manganese complexes have drawn considerable interests in recent years because they can serve as models for active sites of manganese-containing me-talloenzymes,such as photosystem II(PSII),man-ganese superoxide dismutase(MnSOD),manganese ribonucleotide reductase(MnRR)et al[1].The binu-clear manganese enzymes,including catalase,MnRR and arginase,were indicated to have carboxylato-,oxo-,hydroxo-or aquo-bridged cores[2~4].Structures with Mn substituted into the iron ribon…
