Abstract
Poly[(4-3-carboxybenzenesulfonato)silver(I)], Ag(O3SC6H4CO2H) or [Ag(C7H5-
O5S)]n, has been found to undergo a reversible phase transition from monoclinic
to triclinic between 160 and 150 K. The low-temperature triclinic structure
(space group P1) has been determined at 100 K. In contrast to the reported
room temperature monoclinic structure, in which the nearly equivalent
carboxylate C—O distances indicate that the acidic hydrogen is randomly
distributed between the O atoms, at 100 K the C—O (protonated) and C O
(unprotonated) bonds are clearly resolved, resulting in the reduction in
symmetry from C2/c to P1.
