The first anionic dinuclear carbonyl derivative of manganese, (1-), has been prepared by deprotonation of (1) and isolated as its bis(triphenylphosphine)-iminium salt, (2).Complex (2) reacts with complexes of Group 1B and Group 8A matals to give the mixed-metal complexes, , and (μ-PPh2)(CO)8> .Complex (3e) ioneses in solution in the presence of excess PEt3 to give (1+) and (1-).The crystal structures of (2) and (3c) have been determined and are discussed in relation to that of (1), the structure of which has been determined in a different crystalline modification to that previously reported, and to a greater degree of accuracy than that originally achieved.Crystals of (1) are Triclinic, space group C1, with a = 8.157(2), b = 19.246(3), c = 14.510(2) Angstroem, α = 89.10(3), β = 106.31(3), γ = 90.07(3) deg, Z = 4; 2 710 reflections with I >/= 3?(I) , refined to R = 0.0493 and R' = 0.0506.Complex (2) crystallises in space group P21/c with a = 10.172(2), b = 30.441(4), c = 17.076(3) Angstroem, β = 100.88(3) deg, Z = 4; 4 005 reflections /= 3?(I), 3 , refined to R = 0.067 and R' = 0.063.Crystals of (3c) are Monoclinic, soace group P21/c, a = 13.360(2), b = 14.645(1), c = 17.336(3) Angstroem, β = 115.20(1) deg, Z = 4; 1 843 reflections /= 2?(I), 3 , refined to R = 0.079 and R' = 0.065.
