| 摘 要： | 1 INTRODUCTION Diazoles have both a pyridine-type nitrogen and a pyrrole-type nitrogen (imino group), so they can act as bifunctional groups to coordinate with many metal ions or Lewis acids giving a variety of products[1, 2]. Recently researches on the pyrazole ligand have been focused on the following three sections. (i) The first is that the ligand acts as a bridged ligand and coordinates to metal forming di- and polynuclear complexes. Such system arouses much interest mainly because o…

| Abstract: | The complex [Cu(C5H7O2)(C5H8N2)3]Br. C2H5OH was obtained from a reaction of CuBr, acac, and Hdmpz (Hdmpz = 3, 5-dimethylpyrazole) in a mixed solution of ethanol, ether and water. The crystal belongs to monoclinic system, space group P21/n with a = 8.101 (5), b = 19.264(10), c = 17.19(3) (A), β = 95.54(2)°, V = 2670(5) (A)3, Z = 4, Mr = 577.03, Dc = 1.435 g/cm3, F(000) = 1196, μ = 2.348 mm-1, R = 0.0500 and wR = 0.1188 for 5361 observed reflections (I ＞ 2σ(Ⅰ)). The Cu(Ⅱ) ion is coordinated by three Hdmpz and one acac to form a distorted square-pyramid. The complex contains an ethanol molecule and a bromide anion outside acting as the counter ion. |
