摘要： 合成了含有冠醚环化二硫烯的双核Au(I)配合物[(3O-C2S4)Au2(PPh3)2] (1), [(4O-C2S4)Au2(PPh3)2] (2), [(3O-C6S8)Au2(PPh3)2] (3)和[(4O-C6S8)Au2(PPh3)2] (4), 以及一个富硫配合物 [(btdt)Au2(PPh3)2] (5). 通过X射线单晶衍射对配合物1-3和 5 进行了结构表征，并通过循环伏安法研究了这些配合物的氧化还原性质. 研究结果表明配合物 4 对 Na+ 离子有明显的电化学响应，峰电位可以产生大约55 mV的正电位移动.

Abstract: A series of new gold(I) complexes containing crown ether annelated dithiolate ligands, [(3O-C2S4)Au2(PPh3)2] (1, 3O-C2S42?=1,4,7-trioxa-10,13-dithiacyclopentadec-11-ene-11,12-dithiolate), [(4O-C2S4)Au2(PPh3)2] (2, 4O-C2S42?=1,4,7,10-tetraoxa-13,16-dithiacyclooctadec-14-ene-14,15- dithiolate),[(3O-C6S8)Au2(PPh3)2] (3, 3O-C6S82?=2-{4,5-dithia-(3',6',9'-trioxaundecyl)-1,3-dithiol-2- ylidene}- 1,3-dithiol-4,5-dithiolate)), and [(4O-C6S8)Au2(PPh3)2] (4, 4O-C6S82?=2-{4,5-dithia-(3',6',9', 12'-tetr- aoxatetradecyl)-1,3-dithiol-2-ylidene}-1,3-dithiol-4,5-dithiolate); and the sulphur-rich dithiolate gold(I) complex [(btdt)Au2(PPh3)2] (5, btdt=benzotetrathiafulvalenedithiolate), have been prepared and characterized. The crystal structures of complexes 1-3 and 5 have been determined. Redox properties of these compounds have been investigated by cyclic voltammetry and complex 4 shows significant response for Na+ ions with a large positive shift of ca. 55 mV.
