Nonplanar σ^2, π-and Planar σ^2-Enediamide Coordinations of 1, 4-Di(p-methoxyphenyl)-1, 4-diaza-1, 3-butadiene(=MeOC_6H_4-DAD)on Ta(η^5-C_5R_5)Fragments(R=H, Me) : Crystal Structures of TaCl_2(σ^2, π-MeOC_6H_4-dad)(η^5-C_5H_5)and Ta(σ^2-MeOC_6H_4-dad)(η^5-C_5Me_5)(η^4-1, 3-butadiene)

Treatment of TaCl<SUB>4</SUB>(η<SUP>5</SUP>-C<SUB>5</SUB>R<SUB>5</SUB>)[<B>1</B> ; R = H (<B>a</B>), R = Me (<B>b</B>)] with a dilithio compound of 1,4-di(<I>p</I>-methoxyphenyl)-1,4-diaza-1,3-butadiene (abbr. MeOC<SUB>6</SUB>H<SUB>4</SUB>-DAD) gave TaCl<SUB>2</SUB>(σ<SUP>2</SUP>,π-MeOC<SUB>6</SUB>H<SUB>4</SUB>-dad)(η<SUP>5</SUP>-C<SUB>5</SUB>R<SUB>5</SUB>) [<B>2</B>; R = H (<B>a</B>), R = Me (<B>b</B>)]. Complexes <B>2</B> reacted with a magnesium-butadiene compound to afford Ta(σ<SUP>2</SUP>-MeOC<SUB>6</SUB>H<SUB>4</SUB>-dad)(η<SUP>5</SUP>-C<SUB>5</SUB>R<SUB>5</SUB>)(η<SUP>4</SUP>-1,3-butadiene)[<B>3</B>; R = H (<B>a</B>), R = Me (<B>b</B>)]. Crystal structures of <B>2a</B> and <B>3b</B> were determined by X-ray analysis.
