First-row transition metal-halide complexes of tris(2-dimethylaminophenyl)amine, L(Me), have been synthesized and characterized. X-ray crystallographic studies on [Co(L(Me))Br]BPh(4), [Ni(L(Me))Cl]BPh(4), [Fe(L(Me))Cl]BPh(4), and [Cu(L(Me))Cl]BF(4) have been performed, and in all cases the ligand produces five-coordinate complexes with distorted trigonal bipyramidal coordination geometries. Where possible, comparisons have been made to the structures of related neutral tripodal ligands. Spectroscopic and magnetic studies of these complexes are also described. The Cu(I)-carbonyl complexes [Cu(L(Me))(CO)]PF(6) and [Cu(Me(6)tren)(CO)]PF(6) (Me(6)tren = tris(N,N-dimethylaminoethyl)amine) have also been prepared. Infrared spectroscopic investigations of these carbonyl complexes confirm that L(Me) is a less electron donating ligand than Me(6)tren and indicate that L(Me) can impart a different coordination number in the solid-state.
已合成并表征了三(2-二甲氨基苯基)胺(L(Me))的第一过渡金属卤化物配合物。对[Co(L(Me))Br]BPh(4)、[Ni(L(Me))Cl]BPh(4)、[Fe(L(Me))Cl]BPh(4)和[Cu(L(Me))Cl]BF(4)进行了 X 射线晶体学研究,在所有情况下,配体均产生具有扭曲三角双锥配位几何形状的五配位配合物。在可能的情况下,还对相关中性三脚架配体的结构进行了比较。还描述了这些配合物的光谱和磁性研究。还制备了 Cu(I)-羰基配合物[Cu(L(Me))(CO)]PF(6)和[Cu(Me(6)tren)(CO)]PF(6)(Me(6)tren = 三(N,N-二甲基氨基乙基)胺)。这些羰基配合物的红外光谱研究证实,L(Me)是比 Me(6)tren 电子给体能力较弱的配体,并表明 L(Me)可以在固态中赋予不同的配位数。
