SYNTHESIS AND STRUCTURE OF NEW Er(III) COMPLEXESWITH N,N′-1,3-BIS(2,6-DIISOPROPYLPHENYL)TRIAZENIDE

By the interaction of [Er(N(SiMe3)2)3] with HN3Dipp ((N3Dipp)– = N,N′-1,3-bis(2,6-diisopropylphenyl) triazenide) [Er(N3Dipp)(N(SiMe3)2)2] (1) and [Er(N3Dipp)2(N(SiMe3)2)] (2) complexes are obtained. The reaction of 2 with thiophenol gives [Er(N3Dipp)2(SPh)(THF)] complex (3). The structures of the compounds is determined by single crystal Xray diffraction of the following solid phases: 1, 2·C6H6, and 3.
