Abstract

An Organometallic compound, $C_{16}H_{35}B_{10}IrS_2Si$, was synthesized from o-carborane, $Cp^*Ir(S_2C_2B{10}H_{10})$, and $Me_3SiCHN_2$. The molecular structure of this complex has been determined by X-ray diffraction. Crystallographic data : monoclinic, space group $P2_1/n$, $a=10.1986(12)\;{\AA}$, $b=14.834(5)\;{\AA}$, $c=17.139\;{\AA}$, ${\beta}=92.24(2)^{\circ}$, Z=4, $V=2591.0(14)\;{\AA}^3$. The structure was solved by direct methods and refined by full-matrix leat-squares methods to give a model with a reliability factor R=0.053 for 5080 reflections.

유기금속 화합물 $C_{16}H_{35}B_{10}IrS_2Si$를 o-carborane으로 출발하여 $Cp^*Ir(S_2C_2B{10}H_{10})$을 합성하고, $Me_3SiCHN_2$를 가하여 합성하였다. X-선 회절법을 이용하여 $C_{16}H_{35}B_{10}IrS_2Si$ 화합물의 분자구조를 규명하였다. 이 화합물의 결정학적 자료는 monoclinic, space group $P2_1/n$, $a=10.1986(12)\;{\AA}$, $b=14.834(5)\;{\AA}$, $c=17.139\;{\AA}$, ${\beta}=92.24(2)^{\circ}$, Z=4, $V=2591.0(14)\;{\AA}^3$이다. 결정 구조는 직접법으로 해석하였으며, 완전행렬최소자승법을 정밀화 하였으며 5080개의 회절 반점에 대하여 최종 신뢰도 인자 R=0.053인 분자모형을 구하였다.
