[(PNP)TiCl2] (PNP = N[2-PiPr2-4-methylphenyl]2) reacts with one equivalent of lithium derivative of diphosphane R2P-P(SiMe3)LinTHF (R = tBu, iPr) in toluene and forms the first complex with g1-coordination [(PNP)Ti(Cl){g1-P(SiMe3)-PtBu2}] (1) and complex with g2-coordination [(PNP)Ti(Cl){g2-P(SiMe3)-PiPr2}] (2) of phosphanylphosphido ligands to the titanium center. The similar reaction with two equivalents of tBu2P-P(SiMe3)LinTHF in toluene leads to solid 3 which contains 1 and excess of tBu2P-P(SiMe3)Li in the unit cell. In complex 2 disorder of the phosphanylphosphido ligand was observed. The disorder model shows that the phosphanylphosphido ligand coordinates to the metal center alternately as a bidentate and as a monodentate ligand.
