N2  - The crystal structures of the silver(I) complexes with phenoxyacetic acid and 4-fluorophenoxyacetic acid, catena-[ bis-&#956;-(phenoxyacetato-O,O&#8242;)- disiver (I)] (1) and bis [ bis-&#956;(4-fluorophenoxyacetato-O,O&#8242;)-{ aquasilver (I)}] (2) have been determined and refined to residuals R 0.068 and 0.036 respectively for 1783 and 2549 observed reflections. Both structures are based on similar bis ( carboxylato -O,O&#8242;) bridged dimers with Ag-Ag 2.866(2)&#506; (1) and 2.836(2)&#506; (2). However, (1) forms a step polymer through terminal oxygens [Ag-O 2.417, 2.443(9)&#506;], while (2) is a discrete centrosymmetric tetramer with a water molecule on each of the four silver atoms [Ag- Ow 2.499(4)&#506;], and an Ag-O bridge distance of 2.498(4)&#506;. This results in triangular coordination about one silver and tetrahedral about the second. Experimental data indicate that anhydrous silver(I) 4-chlorophenoxyacetate (3) is similar to complex (1).
