Abstract
The S-enantiomer of the 6,6'-dimethyl-2,2'-dia minobiphenyl (dmdabp) has been obtained by resolving dmdabp with l-tartaric acid. The square planar dichloro platinum(II) complex has been prepared with the optically active S-dmdabp, which is found to take the conformation in the [Pt(S-dmdabp)Cl$_2]$ complex.
l-tartaric acid를 이용하여 두자리 아민리간드인 6,6'-dimethyl-2,2'-dia minobiphenyl (dmdabp)를 분할하여 S광학이성질체인 S-dmdabp를 얻었다. S-dmdabp로 부터 평면사각형 착물[Pt(S-dmdabp)Cl$_2]$를 합성하였으며, 이 착물에서 S-dmdabp 리간드가 ${\delta}$-confomation으로 배위 되어 있음을 확인하였다.
