Abstract:
The title compound, [Ag(2)I(2)(C(5)H(5)N)(2)(C(18)H(27)P)(2)], contains centrosymmetric dinuclear species in which each Ag atom is surrounded by a phosphine ligand, a weakly coordinating pyridine ligand and two iodide anions in a distorted tetra-hedral coordination. The two iodide anions bridge the Ag atoms, which are separated by a distance of 3.1008 (6) Å. The Ag-P distance is 2.4436 (8) Å, Ag-N is 2.386 (3)Å and the Ag-I distances are 2.8186 (4) and 2.9449 (5) Å.
