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

The title complex, [Ag(3)Br(2)(C(25)H(22)P(2))(3)]Br·C(7)H(8)N(2)S, comprises a trinuclear [Ag(3)Br(2)(C(25)H(22)P(2))(3)](+) unit, a Br(−) anion and one N,N′-di­methyl­thio­urea mol­ecule (ptu). Three Ag(I) ions are linked via two μ(3)-bridging Br atoms, leading to a distorted triangular bipyramid with an Ag⋯Ag separation range of 3.1046 (6)–3.3556 (6) Å. The triangular Ag(3) arrangement is stabilized by six P atoms from three chelating bis­(di­phenyl­phosphan­yl)methane (dppm) ligands. The Ag(I) ion presents a distorted tetra­hedral coordination geometry. In the crystal, the bromide anion is connected to the ptu mol­ecule through N—H⋯Br hydrogen bonds [graph-set motif R (2) (1)(6)]. Each bromide/ptu aggregate links the complex ion via C—H⋯S and C—H⋯Br hydrogen bonds, leading to the formation of a three-dimensional network. Two phenyl rings from two dppm ligands were modelled as disordered over two sites.
