In recent years, the synthesis of coordination compounds with extended structures has attracted much attention from the viewpoint of nanoscale science, crystal engineering, and solidstate properties. 1 We have demonstrated that a metal-metal dative bond is a useful connector for preparing metal complex assemblages, where the extended structures were constructed by metal-metal dative bonds and normal coordination bonds. 2 In this study, we have prepared metal-metal bonded chain complexes by means of a Pt II fAg + dative bond using [Pt(phpy) 2 ] and [Pt(thpy) 2 ] (Hphpy ) 2-phenylpyridine, Hthpy ) 2-(2-thienyl)pyridine), and report a novel helical 1-D chain complex and

(1,4,7-Trithiacyclononane)silver trifluoromethanesulfonate crystallizes in a tetrameric form from nitromethane, to give the title compound, [Ag(4)(C(6)H(12)S(3))(4)](CF(3)SO(3))(4) x 2CH(3)NO(2). The complex cation consists of four [AgL]+ units (L is 1,4,7-trithiacyclononane), with four Ag-S-Ag bridges forming a cyclic tetramer. The almost planar Ag(4)S(4) ring takes an octagonal form.
