摘要:
A new complex [Cu (C4H7N3) H2O (4,4'-Hbpy)]. SO4. NO3 was synthesized and X-ray characterized. Elemental analysis, Xray diffraction and infrared spectroscopy of the complex were performed. The crystal system is orthorhombic. Crystal data: Fw = 498.98, spacegroup: P212121. Z = 4, a = 14.952(3), b = 20.491(4), c = 6.713 Angstrom. V = 2056.7(9) Angstrom. lambda (Mo-K alpha) = 0.71070 Angstrom. mu = 12.18 cm(-1), D-calc = 1.66 g/cm(3), F-000 = 1032.00, R = 0.062, Rw = 0.087. X-ray analysis illustrated that 4,4'-bpy is mono-protonated and that there are two kinds of anions in one molecule, which give rise to the hydrogen interaction between the molecules in the crystal. Then an extended three-dimensional network is formed along the hydrogen bonds and pi-pi bonds between the pyridine rings. (C) 2001 Elsevier Science B.V. All rights reserved.
