The electrochemical behavior of several complexes with the general formula [M(NO)Cl5-2n(acac)n]m (M=Ru, Os; n=1, 2; acac=acetylacetonato) was investigated: mer-[Ru(NO)Cl3(acac)]- (1, n=1), cis-[Ru(NO)Cl(acac)2] (2, n=2), mer-[Os(NO)Cl3(acac)]- (3, n=1), cis-[Os(NO)Cl(acac)2] (4, n=2). The study includes the known corresponding n=0 complexes, [M(NO)Cl5]2- (M=Ru, Os), for comparison. All these complexes undergo a one-electron oxidation, which is rather unusual redox behavior in the {MNO}6-type nitrosyl complexes. The behavior of some of these complexes as electrophiles was also described. Molecular structures with a meridional configuration were established for the n=1 complexes ([Ru(NO)Cl3(acac)]- (1) and [Os(NO)Cl3(acac)]- (3)) by X-ray structure determinations. Crystal data for 1 (Bu4N salt): C21H43N2O3Cl3Ru, a=31.443(9), b=21.86(1), c=19.852(6) A, β=119.65(2)°, monoclinic, C2/c, Z=16. Crystal data for 3 (Cs salt): C5H7NO3Cl3OsCs, a=7.942(1), b=12.602(2), c=7.451(2) A, α=105.91(2), β=98.20(2), γ=90.31(1)°, triclinic, P1, Z=2.
