PROBLEM TO BE SOLVED: To obtain the subject new compound having a bulky substitution group and useful as a ligand for a metal complex. SOLUTION: This compound is a silicon-containignα-diimine compound of formula I (R and R<1> are each H, methyl, ethyl, n-propyl, phenyl, etc.; R<2> to R<4> are each a 1-10C monovalent hydrocarbon; R<5> is H, a silicon-containing group of the formula R<2> R<3> R<4> Si-, etc.), e.g. N,N'-bis(2-trimethylsilylphenyl) ethylenediamine. The compound of formula I can be obtained, for example, by mixing the aniline derivative of formula H withα-dicarbonyl compound of formula III in an alcohol, or a mixed solvent of an alcohol and water, and carrying out dehydrating condensation of the mixture. The compound is expected to be used as a ligand for a metal complex because the compound has bulky substituting groups at the ortho position of the amino group.
