The crystal structure of silver(I) 2-hydroxybenzoate and silver(I) 2,6-dihydroxybenzoate

Abstract

The crystal structures of silver(I) 2-hydroxybenzoate, (1), and silver(I) 2,6-dihydroxybenzoate, (2), have been determined by X-ray diffraction and refined to residuals of 0.027 and 0.043 for 1183 and 1573 observed reflections respectively. Both form crystals which are monoclinic with 2 centrosymmetric dimers in cells with dimensions a = 7.405(1), b = 8.826(2), c = 10.683(2) Å, β = 107.48(4)°, space group P2₁/c (1) and a = 7.322(1), b = 10.307(2), c = 9.701(2), β = 111.98(2)°, space group P2₁/n (2). The complexes are dimeric with similar Ag —Ag, Ag —O distances and O– Ag —O angles [2.861(1), 2.181(4), 2.202(4) Å, 159.5(2)°, (1) and 2.910(1), 2.203(4), 2.240(4) Å, 160.6(1)° (2)].
