Crystal Structure of [BeCl2(15-Crown-5)] Single crystals of [BeCl2(15-crown-5)] (1) were obtained from dichloromethane solutions of BeCl2 in the presence of the equivalent amount of 15-crown-5 and characterized by IR spectroscopy and X-ray diffraction. Space group P21/c, Z = 4, lattice dimensions at 100 K: a = 1036.2(1), b = 1071.1(1), c = 1360.1(1) pm, β = 109.86(1)°, R1 = 0.0225. The structure determination
[ (15-Crown-5)] 的晶体结构 [ (15-crown-5)] (1) 的单晶是在等量的 15-crown-5 和
BeCl2 的
二氯甲烷溶液中获得的用红外光谱和 X 射线衍射表征。空间群 P21 / c,Z = 4,100 K 时的晶格尺寸:a = 1036.2 (1),b = 1071.1 (1),c = 1360.1 (1) pm,β = 109.86 (1) °,R1 = 0.0225。结构测定显示无紊乱,所有氢位均各向同性地细化。结果与先前报道的空间群 P21nb 中的晶体结构确定相反。1 的
铍原子与末端
氯原子形成 BeO2C2 五元杂环,形成扭曲的四面体配位,距离为 Be – O 166.5 (2), 169.9 (2) pm, and Be – Cl 195.8 (2), 197.8 (2) ) 下午。
