Reactivity of the [Mo3(μ3-S)(μ2-S2)3Br6]2- Aniontoward the ImidodiphosphinochalcogenidoLigands [N(QPPh2)2]- (Q = S, Se): Synthesis andCharacterization of[Mo3(μ3-S)(μ2-S2)3{N(QPPh2)2}3]Br
Reactions of imidodiphosphinochalcogenido ligands [N(QPPh2)2]- (Q = S, Se) with [Mo3(μ3-S)(μ2-S2)3Br6]2- (1) afford the first Mo complexes of such ligands: [Mo(μ3-S)(μ2-S2)3{N(SPPh2)2}3]Br (2) and [Mo3(μ3-S)(μ2-S)3{N(SePPh2)2}3]Br (3). In these complexes the [Mo3(μ3-S)(μ2-S2)3]4+ core is maintained and three [N(QPPh2)2]- ligands are bound to the Mo atoms in a Q,Q‘-bidentate fashion.
