摘要：
Six new coordination complexes [Ag-2(L)(2)](NO3)(2) (1), [Ag-2(L)(2)](ClO4)(2) (2), [Ag-3(L)(4)](SbF6)(3) (3), [Ag-2(L)(2)(CH3CN)(2)](PF6)(2) (4), [Ag-2(L)(2)(SO3CH3)(2)](CH3OH)(2) (5) and [Ag-2(L)(2)(SO3CF3)(2)] (6) were successfully synthesized by reactions of 1,3-bis(2-oxazolinyl) benzene (L) with different Ag(I) salts under the same reaction conditions. Complexes 1 and 2 have the same 16-membered ring structures, which are extended by Ag center dot center dot center dot O weak interactions and hydrogen bonds to form 3D frameworks. Complex 3 containing two- and four-coordinated Ag(I) atoms has two inter-connected 16-membered rings which are linked together by SbF6 to form a 3D framework. In complex 4, the Ag(I) is three-coordinated by two N atoms from the L ligands and one N atom from acetonitrile solvent and the structure of 4 is also a 16-membered ring. Complexes 5 and 6 have similar 16-member ring structure, and the anions coordinate with Ag(I) atoms. The results reveal that anions can influence on the structure of the complexes. Furthermore, the complexes were characterized by electrospray mass spectrometry. (c) 2012 Elsevier B.V. All rights reserved.
