Complexes Ru(DMF){sub 6}{sup n+} (n = 2,3; DMF = N,N-dimethylformamide) are prepared by a direct and simple synthesis from commercially available RuC1{sub 3}{center_dot}xH{sub 2}O and characterized by UV-vis, NMR, and cyclic voltammetry. Crystal and molecular structures are presented for [Ru(DMF){sub 6}](CF{sub 3}SO{sub 3}){sub 3} (I) and [Ru(DMF){sub 6}](CF{sub 3}SO{sub 3}){sub 2} (II). I is monoclinic, of space group P2{sub 1}/c, with a = 18.28(1) {angstrom}, b = 18.62(1) {angstrom}, c = 13.29(1) {angstrom}, {beta} = 100.8(1){degrees}, V = 4443(5) {angstrom}{sup 3}, Z = 4, d{sub calc} = 1.495 g cm{sup -3}, and d{sub obs} = 1.49 (25{degrees}C) g cm{sup -3}. R = 0.061 (R{sub w} = 0.061) for 4506 independent observed reflections with I > 3{sigma}(I). II is triclinic, of space group P{bar 1}, with, a =8.799(2) {angstrom}, b = 9.557(2) {angstrom}, c = 11.627(2) {angstrom}, {alpha} = 76.11(2){degrees}, {beta} = 8473(2){degrees}, {gamma} = 85.12(2){degrees}, V = 943.1(3){angstrom}{sup 3}, Z = 1, d{sub calc} = 1.475 g cm{sup -3}, and d{sub obs} = 1.477 (25{degrees}C) g cm{sup -3}. R = 0.061 (R{sub w} = 0.058) for 5189 independent observed reflections with I > 3 {sigma}(I). Metal to ligand coordination is through the oxygen atom with average Ru-O distances of 2.02(1)more » {angstrom} (I) and 2.088(9) {angstrom} (II) in the octahedral units.
