摘要：

In the title two-coordinate silver compound, [Ag(C3H9P)(2)]PF6, the cation has crystallographically imposed mirror symmetry, and approximates very closely to (3) over barm (D-3d) symmetry with fully staggered methyl groups in the solid state. The Ag atom has a nearly linear coordination geometry, with a P-Ag-P angle of 178.70 (4)degrees. The Ag-P bond lengths are 2.3746 (12) and 2.3783 (12) Angstrom, which are significantly longer than the Au-P bond length of 2.304 (1) Angstrom in the analogous two-coordinate gold cation. The lack of intramolecular steric effects within the present cations containing trimethylphosphine (cone angle 118degrees), compared with those in known cations containing trimesitylphosphine (cone angle 212degrees), provides a better comparison of M-P distances and thus more conclusive evidence that Au really is smaller than Ag.
