摘要：

Comparative analysis of the donor-acceptor capacities of diphosphine ligands in two series of complexes: cis-[Ru(bpy)(2)(LL)](q+) [LL = 2,2'-bipyridine (bpy), o-benzoquinonediimine (bqdi), cis-1,2-bis(diphenylphosphino)ethane, cis- 1,2-bis(diphenylphosphino)ethylene (dppen), (NH3)(2), and (CO)(2)] and [Ru(NH3)(4) . (LL)](2+) (LL = bpy, dppen, and bqdi), was performed. Diphosphines are the strongest a donors; they compare in pi-acceptor capacity which is associated with phosphorus d orbitals with 2,2'-bipyridine and fall far short of o-benzoquinonediimine and carbonyl.
