The　title　complex,　[Ag2(C25H22P　2)2(C9H7N)2](CF　3SO3)2·C9H7N,　was　prepared　by　the　reaction　of　silver(I)　trifluoro-methane-sulfonate　with　isoquinoline　and　bis-(diphenyl-phosphan-yl)methane　(dppm).　The　dinuclear　mol-ecule　is　located　about　a　center　of　inversion　and　the　AgI　atom　is　coordinated　by　two　dppm　P　atoms　and　one　isoquinoline　N　atom,　forming　an　eight-membered　metalla　ring.　In　addition,　in　the　asymmetric　unit,　there　is　a　half-mol-ecule　of　isoquinoline　located　about　a　center　of　inversion.　Since　this　mol-ecule　does　not　possess　this　symmetry,　for　one　position　in　the　ring　there　is　superposition　of　both　a　C　atom　of　a　C-H　group　and　the　isoquinoline　N　atom.　In　the　structure,　the　Ag-P　distances　[2.4296　(9)　and　2.4368　(9)　Å]　agree　with　the　corresponding　distances　in　related　structures,　while　the　Ag-N　bond　length　[2.489　(3)　Å]　is　slightly　longer　than　that　in　related　structures.　On　the　other　hand,　the　P-Ag-P　angle　[156.44　(3)°]　is　much　larger　than　the　corresponding　angles　in　related　structures.　The　trifluoro-methane-sulfonate　anions　do　not　coordinate　to　AgI　atoms.　As　is　usually　found　for　these　anions,　the-CF3　group　is　disordered　over　two　orientations　[occupancies　=　0.57　(12)　and　0.43　(12)].
