Abstract

The structure of C_{28}H_{41}N_4O_4Br\;{\cdot}\;2H_2O$ has been determined by X-ray deffraction methods. The crystal system is triclinic, space group Pl, unit cell constants, a=9.000(1) $\AA$, b=9.312(3) $\AA$, c=9.344(2) $\AA$, $\alpha=89.37(20)^{\circ},\;\beta=68.81(3)^{\circ},\;\gamma=84.70(4)^{\circ},\;V=726.7(8){\AA},\;T=298K,\;Z=1,\;D_c=1.402Mgm^{-3}$. The intensity data were collected on an Enraf-Nonius CAD4 Diffractometer with graphite monochromated $MoK\alpha$ radiation $(\lambda=0.71073\;{\AA}$. The molecular structure was solved by direct methods and refined by full-matrix least squares to a final $R=5.95\%$ for 2521 unique observed $F_0>4\sigma(F_0)$reflections and 370 parameters.

X-선 회절법을 이용하여 C_{28}H_{41}N_4O_4Br\;{\cdo}t\;2H_2O$의 분자 및 결정구조를 해석하였다. 이 결정의 결정계는 Triclinic이고 공간군은 Pl이며, 단위포 상수 a=9.000(1) $\AA$, b=9.312(3) $\AA$, c=9.344(2) $\AA$, $\alpha=89.37(20)^{\circ},\;\beta=68.81(3)^{\circ},\;\gamma=84.70(4)^{\circ},\;V=726.7(8){\AA},\;T=298K,\;Z=1,\;D_c=1.402Mgm^{-3}$이다. 회절반점들의 세기는 Enraf-Nonius CAD4 Diffractometer로 얻었으며 사용한 X-선은 graphite로 단색화한 $MoK{\alpha}$$(\lambda=0.71073\;{\AA}$을 사용하였다. 분자구조는 Direct method로 풀었으며, $F_o>4{\sigma}(F_0)$인 2521개의 독립 회절 데이터에 대하여 최소 자승법으로 370개의 변수를 정밀화하여 최종 신뢰도 값 $R=5.95\%$를 얻었다.
