|Abstract:||The reaction of the ligand diphenyl(2-pyridyl)phosphine (L) with HAuCl4 and AgCl affords the complexes [AuClL] and [Ag2Cl2L3] respectively. The crystal structures of these two complexes have been determined from four-circle diffractometer data; [AuClL] is orthorhombic, space group Pnma, with a = 11.774(3), b = 12.617(3), and 11.114(6) Å, Z = 4, and R = 0.052 for 1 358 observed reflections; [Ag2Cl2L3] is monoclinic, space group P21/c with a = 14.599(3), b = 18.388(5), and c = 21.134(4) Å, β = 125.12(1)°, Z = 4, and R = 0.060 for 5 180 observed reflections. In the gold complex the phosphorus of L alone is bonded to the gold atom which assumes a linear geometry with Au-Cl 2.286(4) Å and Au-P 2.234(4) Å. The silver complex contains molecules in which two silver atoms are held together by two chloride bridges. One of the silver atoms is bonded to two L molecules through the phosphorus atom, while the other silver atom is bonded to a L molecule as well as loosely bonded to the nitrogen atom of one of the ligands co-ordinated to the first silver atom. The silver atoms assume a tetrahedral co-ordination with Ag-Cl 2.701(4), 2.618(8), 2.638(4), and 2.601(9) Å; Ag-P 2.432(3), 2.436(4), and 2.452(3) Å; and Ag-N 2.451(9) Å.|
