The mononuclear adducts chloro- and bromo-pyridinebis(triphenylphosphine)silver(I) have been synthesized and structurally characterized by single-crystal X-ray diffraction methods.The two complexes are isomorphous, monoclinic, space group P21 or P21/m, a ca. 9.8, b ca. 20.0, c ca. 9.1 Angstroem, β ca. 97.5 deg, Z 2; in space group P21/m, they were refined to residuals of 0.038, 0.036 for 2392, 2157 'observed' reflections respectively.No comparable iodide adduct has been isolated.In both structures the silver atom is four-coordinate; Ag-Cl,Br are 2.511(2), 2.629(1) Angstroem; Ag-P, 2.472(1), 2.476(1) Angstroem, and Ag-N, 2.585(5), 2.570(5) Angstroem respectively, the Ag-N distance being longer than Ag-P, indicating very weak coordination of the pyridine.
