X-ray crystal structure of [L2Ag3]+[OTf]−·5C6D6: a monoanionic bis­­phosphinimine ligand supported tris­­ilver complex

Abstract

The compound bis­{μ3-2,5-bis­[N-(4-iso­propyl­phen­yl)-P,P-di­phenyl­phospho­r­im­i­do­yl]pyrrol-1-ido-κ3N:N′:N′′}tris­ilver(I) tri­fluoro­methane­sulfonate deuterated benzene penta­solvate, [Ag3(C46H44N3P2)2](CF3O3S)·5C6D6, (I), was synthesized from two equivalents of NaL [L = 2,5-(4-iPrC6H4N=PPh2)C4H2N] and three equivalents of AgOTf (OTf = OSO2CF3). High-quality crystals of (I) formed with five deuterated benzene solvent mol­ecules in the asymmetric unit. Notably, the bond lengths and angles between the three silver atoms are markedly different, unlike in most other reported tris­ilver complexes that tend to form three equivalent metal centers. Additionally, to the best of our knowledge, this is the first report of a tris­ilver complex with six nitro­gen donors from two bis­phosphinimine ligands.
