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

ABSTRACT: The title complex, [Ag3I2(C25H22P2)3]I·C7H8N2S, comprises a trinuclear [Ag3I2(C25H22P2)3](+) unit, an I(-) anion and one N,N'-phenyl-thio-urea mol-ecule (ptu). Two ?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 tetra-hedral geometry, with coordination to two I atoms and two P atoms from bis-(di-phenyl-phosphan-yl)methane ligands. In the crystal, the I(-) anion is linked to the ptu mol-ecule 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).
