The structure of cis-trans-(bipyridine-N,N')dicarbonyl-[diphenyl(2-phenyl-4,4,6,6-tetrachloro-2-cyclotriphos-phazenyl)phosphine-P](triphenyl phosphite-P)manganese(I) hexafluorophosphate, [Mn(C18H15O3P)(C10H8N2)(C18H15Cl4N3P4)(CO)(2)]PF6, consists of discrete complex cations and PF6- anions linked by several weak C-H...O and C-H...F interactions. The cation is a very distorted octahedral manganese-dicarbonyl fragment having cis-trans stereochemistry and bearing triphenylphosphite, bipyridine and phosphazenylphosphine [N3P3Cl4(Ph)(PPh(2))] ligands. Analysis of the structure of the complex reveals that the coordination of the phosphazenylphosphine ligand to the cationic manganese-carbonyl fragment induces only minor changes in the phosphazene ring, affecting only the P5-P3 bond length.
