Crystal structure of tris-[?2-bis-(di-phenyl-phosphan-yl)methane-?(2) P:P']di-?3-bromido-tris-ilver(I) bromide-N,N'-phenyl-thio-urea (1/1).

ABSTRACT: 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 ?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 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.
