摘要:
Five novel silver(I) complexes and two copper(I) phosphine complexes containing the bis[2-(diphenylphosphino)phenyllether ligand were synthesized and structurally characterized. Treatment of AgX/CuX and the bis[2-(diphenylphosphino)phenyl]ether with N boolean AND N ligands afforded the silver(I) or copper(I) complexes {[Ag-2(P)(2)(dpa)(H2O)(2)](dpa)(ClO4)(2)}(n) (1), {[Ag(POP)(dpp)](ClO4)}(n) (2), [Ag-2(POP)(2)(4,4'bipy)(CH3CN)(2)](CF3SO3)(2)center dot CH3CN (3), {[Ag(POP)(dpe)](CF3SO3)center dot CH3CN}(n) (4), {[Ag-2(POP)(2)(dpe)(H2O)(2)](dpe) (BF4)(2)}(n) (5), [Cu(POP)(bpy)](BF4) (6) and [Cu-2(POP)(2)(4,4'-bipy)](CF3SO3)(2)center dot 4CH(3)CN (7) {POP = bis[2-(diphenylphosphino)phenyllether; dpp = 1,3-bis(4-pyridyl)propane; dpa = 1,2-bis(4-pyridyl)ethane; dpe = 1,2-bis(4-pyridyl)ethene; 4,4'-bipy = 4,4'-bipyridine; bpy = 2,2'-bipyridine}. These complexes are all characterized by IR, elemental analysis, X-ray diffraction, luminescence, P-31 NMR and H-1 NMR spectroscopy. Complex 5 has an irregular (6,3) network structure connected through hydrogen bonds between the C-H groups of aromatic rings and anions; complexes 1 and 2 are of 2D topological architectures which are linked by hydrogen bonds; complex 4 is of a 1D infinite zigzag chain structure formed by the bridging ligand dpe; complexes 3 and 7 are of dinuclear structures and complex 6 is of mononuclear structure. The choice of solvent and the type and coordination modes of the bipyridine derivatives are of importance in defining the structural and topological features of the resulting networks. In addition, the complexes 1-7 exhibit interesting luminescence in the solid state at room temperature. At the same time, we also studied the terahertz spectrum which provided some new informations of these complexes. (C) 2016 Elsevier Ltd. All rights reserved.
