Bis[μ-bis­(diphenyl­phosphan­yl)methane-κ(2) P:P′]bis­[(isoquinoline-κN)silver(I)] bis­(trifluoro­methane­sulfonate)–isoquinoline (1/1)

The title complex, [Ag(2)(C(25)H(22)P(2))(2)(C(9)H(7)N)(2)](CF(3)SO(3))(2)·C(9)H(7)N, was prepared by the reaction of silver(I) trifluoro­methane­sulfonate with isoquinoline and bis­(diphenyl­phosphan­yl)methane (dppm). The dinuclear mol­ecule is located about a center of inversion and the Ag(I) 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-mol­ecule of isoquinoline located about a center of inversion. Since this mol­ecule 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 trifluoro­methane­sulfonate anions do not coordinate to Ag(I) atoms. As is usually found for these anions, the –CF(3) group is disordered over two orientations [occupancies = 0.57 (12) and 0.43 (12)].
