Abstract

An organometallic compound, $(C_{16}H_{21}B_{10}BrOSn)$, was synthesized from o-carborane, closo-1-[(methoxyl)methyl]-o-carborane $(HCab^o)$, and $SnMe_2Br_2$. The molecular structure of this complex has been determined by X-ray diffraction. Crystallographic data: orthorhombic, space group Pna2, a = 17.9292(15)$\AA$, b= 7.2066(4)$\AA$, c=13.0582(10)$\AA$, Z=4, V=1687.2(2) $\AA^3$. The structure was solved by direct methods and refined by full-matrix least-squares methods to give a model with a reliability factor R=0.0574 for 1724 reflections.

유기금속 화합물 $(C_{16}H_{21}B_{10}BrOSn)$를 o-carborane으로부터 출발하여 closo-1-[(methoxyl) methyl]-o-carborane$(HCab^o)$를 합성하고, $SnMe_2Br_2$을 가하여 합성하였다. X-선 회절법을 이용하여 $(C_{16}H_{21}B_{10}BrOSn)$ 화합물의 분자구조를 규명하였다. 이 화합물의 결정학적 자료는 orthorhombic, space group Pna2, a =17.9292(15)$\AA$, b= 7.2066(4)$\AA$, c=13.0582(10)$\AA$, Z=4, V=1687.2(2)$\AA^3$이다. 결정 구조는 직접법으로 해석하였으며, 1724개의 회절 반점에 대하여 최종 신뢰도 인자 R=0.0574인 분자 모형을 구하였다.
