Coordination chemistry of the solvated silver(I) ion in the oxygen donor solvents water, dimethyl sulfoxide, and N,N '-dimethylpropyleneurea

Persson I, Nilsson KB

Sammanfattning

The hydrated and dimethyl sulfoxide and N, N'-dimethylpropyleneurea solvated silver(I) ions have been characterized structurally in solution by means of extended X-ray absorption fine structure (EXAFS) and large-angle X-ray scattering (LAXS). The coordination chemistry of the hydrated and dimethyl sulfoxide solvated silver(I) ions has been reevaluated because of different results from the EXAFS and LAXS methods reported previously. Consistent results are obtained with a linearly distorted tetrahedral model with two short and approximately two long Ag-O bond distances: mean Ag-O bond lengths of 2.32(1) and 2.54(1) angstrom for the hydrate, 2.31(1) and 2.48(2) angstrom for the dimethyl sulfoxide solvate, and 2.31(1) and 2.54(2) angstrom for the N, N'-dimethylpropyleneurea solvate, in solution
