Treatment of UCl4 or ThCl4 with Li2[Me3SiN{CH2CH2NSiMe 3}2] affords the mono-diamidoamine complexes [M(Me3SiN{CH2CH2NSiMe3} 2)Cl2(THF)] (M=U, Th), and also the bis-diamidoamine complexes [M(Me3SiN{CH2CH2NSiMe3} 2)2] (M=U, Th). The base-free complex [U(Me3SiN{CH2CH2NSiMe3} 2)Cl2]2 was obtained by treatment of [U(Me3SiN{CH2CH2NSiMe3} 2)Cl2(THF)] with hot toluene. The X-ray structures of [Th(Me3SiN{CH2CH2NSiMe3} 2)Cl2(THF)] and [U(Me3SiN{CH2CH2NSiMe3} 2)Cl2]2 reveal a distorted octahedral geometry, whereas [M(Me3SiN{CH2CH2NSiMe3} 2)2] (M=U, Th) display trigonal bipyramidal geometry at the metal centre and the amino group on one of the diamidoamine ligands is non-bonding.
