| 摘 要： | 1 INTRODUCTION Recently, there has been increasing interest in crystal engineering of supramolecular architectures by means of covalent bonding, hydrogen bonding or other weak intermolecular interactions1, 2], which reflect their potential applications in host-guest che- mistry, catalysis and function materials3～5]. The construction of such materials is mainly provided by geometry of transition metal extending through rigid ligands. The oxidation state and coordination predisposition …

Hydrothermal Synthesis and Structure of a Copper(II) Complex, [Cu(4,4'-bpy)(H2O)3]SO4·2H2O |

| Abstract: | The title complex Cu(4,4'-bpy)(H2O)3]SO4@2H2O (Mr = 405.86) was synthesized under hydrothermal conditions and its crystal structure has been determined by X-ray diffraction. It crystallizes in the hexagonal system, space group P61 with a = 11.1870(4), c = 21.578(1)(A°), V = 2338.6(2)(A°)3, Dc = 1.729 g/cm3, Z = 6, ((MoKα) = 1.583 mm-1 and F(000) = 1254. The final R and wR are 0.0253 and 0.0416 for 1458 observed reflections with I≥2((I), respectively. It was revealed that the square pyramidal Cu(II) sites are linked through 4,4'-bipyridine groups, forming infinite one-dimensional chains, with the sulfate anions and lattice water molecules occupying the inter-chain positions. During the electrostatic interactions, there exist O...O hydrogen bonds and π-πstacking interactions between the parallel aromatic bipy rings in the structure. |
