β-structure for a planar sulphur heterocycle. A representative compound is the title thione 2. Crystals of 2 are monoclinic, P21/n, Z=8, a=17.327(4), b=3.950(2), c=27.877(6) Å, B=93.88(2)°; R=0.050, Rw=0.044 on 783 non-zero reflections. Molecules related by translation along [010] are within photoreactive distance and the β-structure leads to the rapid formation on UV irradiation of a fused tricyclic
弱而有方向性的特定堆栈间S .... S和S .... Cl接触可用于设计平面硫杂环的4Å-短轴β结构。代表性的化合物为标题硫酮2。2的晶体为单斜晶体,P2 1 /n,Z=8,a=17.327(4),b=3.950(2),c=27.877(6)Å,B = 93.88( 2)°;R = 0.050,R瓦特= 0.044 783上非零反射。通过沿着[010]的平移而相关的分子在光反应距离之内,并且β结构导致在紫外辐射下快速形成稠合的三环镜对称的环丁烷3。该二聚体非常不稳定并且热分解为新颖的十元二烯烃4。其他一些相关的硫杂环化合物都采用β堆积模式。
