Zusammenfassung: | New vanadium(V) complex, $(NH_4)_2[VO_2NTA]$, has been synthesized and its structure has been determined by solution and solid-state NMR spectroscopies as well as X-ray crystallography. The unit cell of the monoclinic crystals contains four complexes with $a=6.923(1){\AA}$, $b=8.824(2){\AA}$, $c=19.218(11){\AA}$ and ${\beta}=91.60(3)^{\circ}$ in the space group of $P2_1/n$. The $[VO_2NTA]^{2-}$ anion has distorted octahedral geometry with cis-$VO_2$ moiety. It is confirmed that the octahedral geometry is retained in both of solution and solid-state complexes. 새로운 바나듐(V) 착물인 $(NH_4)_2[VO_2NTA]$를 합성한 후, 용액 및 고체핵자기공명분광법 및 X-선회절법으로 그 구조를 측정하였다. 그 결과 단사결정구조(space group=$P2_1/n$)의 이 착물의 단위세포는 4 착물을 가지고 있으며, 그 파라미터는 다음과 같다 : $a=6.923(1){\AA}$, $b=8.824(2){\AA}$, $c=19.218(11){\AA}$, ${\beta}=91.60(3)^{\circ}$, 용액 및 고체에서 이 착물의 $[VO_2NTA]^{2-}$ 이온은 시스-$VO_2$ 단위를 가진 찌그러진 팔면체 구조를 가지고 있음을 알 수 있었다. |
