Abstract
AbstractAddition LiNHPh to a [(NacNac)Cr(μ-I)] 2 [NacNac = 2,4 pentane-N-N′-bis(2,6-diisopropylphenyl) ketiminato] in THF yields a dimeric anilido complex, 1, that crystallizes in P2 1 /n with unit cell parameters a = 13.390(2) A, b = 26.298(5) A, c = 21.326(4) A, β = 93.905(4)°, V = 7492(2) A 3 and Z = 4. The same reaction in the presence of aniline yields a monomeric anilido complex, 2, with a coordinated aniline molecule. Complex 2 crystallizes in P2 1 /c with unit cell parameters a = 28.530(5) A, b = 10.8116(18) A, c = 26.492(5) A, β = 115.685(3)°, V = 7364(2) A 3 and Z = 8. Addition of aniline to isolated 1 yields 2. Addition of LiNPh 2 to [(NacNac)Cr(μ-I)] 2 in THF yields a monomeric complex that crystallizes in P2 1 /n with the unit cell parameters a = 11.152(6) A, b = 23.820(12) A, c = 17.915(9) A, β = 106.223(9)°, V = 4569(4) A 3 and Z = 4. All complexes have been spectroscopically and structurally characterized.Graphical AbstractAddition of LiNHPh or LiNPh 2 to [(NacNac)Cr(μ-I)] 2 yields a dimeric or a monomeric complex whereas addition of LiNHPh in the presence of aniline yields the monomeric anilido complex.[IMAGE]
