The coordination preference of the ketoiminato ligand, RN(H)(C(Me))2C(Me)O, (R = 2,6-diisopropylphenyl, (Dipp)), L1, and RN(H)C(Me)CHC(Me)O, R = C2H4NEt2, L2, have been investigated with a range of d and p block metal halides, (or alkyls), to compare and contrast products obtained from the bulky ketoiminato ligand, L1, versus the less bulky, but multidentate ligand, L2. The products have been characterized
酮氨基配体RN(H)(C(Me))2 C(Me)O,(R = 2,6-二异丙基苯基(Dipp)),L 1和RN(H)C(Me )研究了CHC(Me)O,R = C 2 H 4 NEt 2,L 2与一系列d和p嵌段金属卤化物(或烷基)的比较,以比较和对比从庞大的ketoiminato配体获得的产物, L 1与体积较小但多齿的配体L 2相比。该产品已通过X射线晶体学以及其他光谱技术进行了表征,并显示了具有任何一种配体的产品的优选金属几何形状如何保持恒定,但是各个配体提供的空间保护作用决定了产品的核化,从而提供了单体,二聚体和四聚体。
