Crystal structure of tris[μ2-bis(diphenylphosphanyl)methane-κ2 P:P′]di-μ3-bromido-trisilver(I) bromide–N,N′-phenylthiourea (1/1)

چکیده
The title complex, [Ag3Br2(C25H22P2)3]Br·C7H8N2S, comprises a trinuclear [Ag3Br2(C25H22P2)3](+) unit, a Br(-) anion and one N,N'-di-methyl-thio-urea mol-ecule (ptu). Three Ag(I) ions are linked via two μ3-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 Ag3 arrangement is stabilized by six P atoms from three chelating bis-(di-phenyl-phosphan-yl)methane (dppm) ligands. The Ag(I) ion presents a distorted tetra-hedral coordination geometry. In the crystal, the bromide anion is connected to the ptu mol-ecule 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.
