Abstract
Silver(I) 3-pyridinesulphonate is tetragonal (space group, I 4 ̄ ) with a = 12.316(2) A ̊ , c = 9.007(3) A ̊ and Z = 8. Intensities using Mo K \\ ̄ ga radiation were collected on an automatic four-circle diffractometer. The structure was determined by means of the Patterson function and Fourier syntheses. An anisotropic full matrix least-squares refinement yielded a final R value of 0.039 for the 1561 observed reflections. Within the crystal there are three types of silver atoms located as follows: on 2d positions with a nearly square planar arrangement of oxygen atoms ( Ag-O = 2.369(3) A ̊ ); on 2b positions with a nearly regular tetrahedron of oxygen atoms ( Ag-O = 2.376(3) A ̊ ); on 4f positions with a nearly linear arrangement with two nitrogen atoms ( Ag-N = 2.139(3) A ̊ ). The 2d and 4f silver atoms form linear chains with Ag-Ag distances of 2.982(8) and 3.0125(5) Å. A comparison of the AgO 4 and AgN 2 environments in various compounds is made.
