摘 要: | 1 INTRODUCTION The rational design and synthesis of new metal- organic frameworks have generated considerable interest in supramolecular chemistry and materials science owing to their intriguing structural diver- sities and potential applications as functional mate- rials[1~6]. Carboxylate-containing ligands have attrac- ted considerable attention because of the various coordination modes of carboxylate group, the ability to form hydrogen bonds and the potential applica- tions as functio…

Abstract: | The reaction of Ni(CH3COO)2'6H2O, 4-hydroxycinnamic acid (Hhca) and 4,4'-bipyri- dine (bipy) ligand in water-solution afforded a mononuclear complex [Ni(H2O)4(4,4'-bipy)2](hca)2 which was characterized by IR, elemental analysis, TGA and single-crystal X-ray diffraction. X-ray crystallography analysis reveals that the complex is of triclinic, space group P1 with a = 7.0238(14), b = 7.2934(11), c = 17.186(4) ', α = 87.073(13), β = 84.354(10), γ = 81.961(12)°, V = 866.9(3) '3, Z = 1, Dc = 1.474 g/cm3, F(000) = 402, μ = 62.7 mm-1, R = 0.0411, wR = 0.0862 and GOF = 1.048. In solid state, the cation [Ni(H2O)4(4,4'-bpy)2]2+ connects six nearby hca counter anions via O-H···O hydrogen bonds to form an extended 2D lattice framework and the O-H…N hydrogen bonds finally link the 2D layers into an infinite 3D network. |
