(phosphazido)indenyl complexes 1-[BnN3-κN(Ph2)P]-η5-C9H6}1-[BnN3-κ2N,N′(Ph2)P]C9H6}LnIIIN(SiMe3)2, Ln = La (3-La), Sm (3-Sm), respectively. The five complexes catalyse the intramolecular hydroamination/cyclisation of 2,2-diphenylpent-4-ene-1-amine using 2% catalyst loading. All compounds were characterised by NMR and UV-Vis spectroscopy, single-crystal X-ray diffraction, and elemental analysis and DFT
