Cl3SnCH2CH2CO2Pri-i are orthorhombic, space group P212121 with a 9.638(6), b 10.004(7) and c 12.848(8) Å. The tin atom is five-coordinate with two chlorines and carbon equatorial and the remaining chlorine and the carbonyl oxygen axial, in a distorted trigonal-bipyramidal arrangement: (SnCl)ax 2.389(3), average (SnCl)eq 2.320(2), SnC 2.142(9), SnO 2.337(5) Å. Apart from the equatorial chlorine and the terminal carbons
Cl 3 SnCH 2 CH 2 CO 2 Pri-i的晶体是正交晶体,空间群P 2 1 2 1 2 1 1,具有9.638(6),b 10.004(7)和c 12.848(8)。锡原子是五坐标的,带有两个氯和赤道碳,其余的氯和羰基氧的轴向呈扭曲的三角-双锥体排列:(SnCl)ax 2.389(3),平均(SnCl)eq2.320(2),SnC2.142(9),SnO2.337(5)Å。除了赤道氯和异丙基中的末端碳外,所有非氢原子基本上都是共面的。该分子达到C 2 v对称性,尽管不受结晶空间群的约束。
