Crystal structure of tris­[μ(2)-bis­(di­phenyl­phosphan­yl)methane-κ(2) P:P′]di-μ(3)-iodido-tris­ilver(I) iodide–N-phenyl­thio­urea (1/1)

The title complex, [Ag(3)I(2)(C(25)H(22)P(2))(3)]I·C(7)H(8)N(2)S, comprises a trinuclear [Ag(3)I(2)(C(25)H(22)P(2))(3)](+) unit, an I(−) anion and one N,N′-phenyl­thio­urea mol­ecule (ptu). Two μ(3)-bridging I(−) anions are linked by three Ag(I) ions, leading to the formation of a dicapped triangular motif with Ag⋯Ag separations in the range 3.0823 (5)–3.2999 (5) Å. Each Ag(I) atom exhibits a distorted tetra­hedral geometry, with coordination to two I atoms and two P atoms from bis­(di­phenyl­phosphan­yl)methane ligands. In the crystal, the I(−) anion is linked to the ptu mol­ecule through two N—H⋯I hydrogen bonds [graph-set motif R (2) (1)(6)]. These N—H⋯I hydrogen bonds, in addition to weak C—H⋯S and C—H⋯I hydrogen bonds, form zigzag chains along [010]. Two of the phenyl rings of two dppm ligands are disordered over two sets of sites with refined occupancies of 0.557 (16) and 0.443 (16).
