A series of four tripodal phosphine oxideligands, (OPR2)2CHCH2POR2 (1a–1d), and four mixedphosphine–phosphineoxideligands, (OPR2)2CHCH2PR2 (3a–3d), were synthesized and coordinated to yttrium to produce Y(NO3)3[(OPR2)2CHCH2POR2] (2a–2d) and Y(NO3)3[(OPR2)2CHCH2PR2](OPPh3) (4a–4d) complexes. The previously reported ligand 1a and unknown phosphine oxideligands 1b–1d were generated in an unprecedented
