Abstract

An Organometallic compound, $C_{12}H_{20}B_{10}S_2Co_2$, was synthesized from o-carborane, $Cp^*Co(S_2B_2B_{10}H_{10})$ and $BH_3{\cdot}THF$. The molecular structure of this complex has been determined by X-ray diffraction. Crystallographic data: monoclinic, space group Cc, a=15.981(4) ${\AA}$, b=15.478(17) ${\AA}$, c=12.0562(17) ${\AA}$, ${\beta}=115.063(16)^{\circ}$, Z=4, V=9683(4) ${\AA}^3$. The structure was solved by direct methods and refined by full-matrix leat-squares methods to give a model with a reliability factor R = 0.0630 for 9948 reflections.

유기금속 화합물 $C_{12}H_{20}B_{10}S_2Co_2$를 o-carborane으로 출발하여 $Cp^*Co(S_2B_2B_{10}H_{10})$을 합성하고, $BH_3{\cdot}THF$를 가하여 합성하였다. X-선 회절법을 이용하여 $C_{12}H_{20}B_{10}S_2Co_2$ 화합물의 분자구조를 규명하였다. 이 화합물의 결정학적 자료는 monoclinic, space group Cc, a=15.981(4) ${\AA}$, b=15.478(17) ${\AA}$, c=12.0562(17) ${\AA}$, ${\beta}=115.063(16)^{\circ}$, Z=4, V=9683(4) ${\AA}^3$이다. 결정 구조는 직접법으로 해석하였으며, 완전행렬최소자승법을 정밀화 하였으며 9948개의 회절 반점에 대하여 최종 신뢰도 인자 R=0.0630인 분자모형을 구하였다.
