Dimeric iodo[bis(diphenylphosphinoethyl)sulphido]silver

Abstract

Abstract. (AglPzSCzsHzs)2, triclinic, PT, a = 11.796 (2), b=10.108 (2), c=12.332 (3) ,A,, ~=96.45 (2), fl= 102.95 (3), 7=94.84 (2) °, V= 1415 .h3, Z= 1, DoRic= 1"62, Dobs = 1"61 g cm -3. Bis(diphenylphosphinoethyl) sulphide, [(C6Hs)2PC2H4]2S, acts as a bidentate bridging ligand with the two P atoms coordinating different Ag atoms. The S to Ag distances imply no coordination between these atoms. The ligands are connected twoand-two by P-Ag-P bonds. The Ag atoms are also joined by a double I bridge. The crystal structure is thus built up by discrete dimeric molecules, (AgIPzSCzsH2s)2. A comparison is made between the structures of the isotypic compounds (AgXPzSCzsH28)2, X = I and CI.

“…The C-C distances in the phenyl rings average 1"382 (7) and 1.383 (12) A respectively, in good agreement with values reported for similar compounds, e.g. (AgIP2SC28H2s)2 (Cassel, 1975). The largest deviations of a C atom from the least-squares planes through C(1)-C(6) and C(7)-C(12) of the two phenyl rings are 0-006 and 0.008 A.…”

“…Besides being bonded to two I atoms, Hg is coordinated to the two P atoms and Ni to the two P atoms and the S atom of one ligand molecule. The Ag complex (Aurivillius, Cassel & Faith, 1974;Cassel, 1975) is built up of dimeric molecules (AgXP2SC28H28)2, X--CI, I. The Ag atom is coordinated to two X atoms and to two P atoms, belonging to two different ligand molecules.…”

“…1. As in (AgXP2SC2sH28)2, X = C1 and I (Aurivillius, Cassel & F/ilth, 1974;Cassel, 1975), the present non-hydrogen atoms except the phenyl carbon atoms. The smallest and largest angles of the distorted tetrahedra around Ag(1), Ag(2), P(1), P(2), P(3) and P(4) are given.…”
