Abstract

The crystal structure of [Li(HL)] (H2L = 2,2′-(biphenyl-2,2′-diylbis(oxy))diacetic acid) was studied by X-ray diffraction methods. This complex crystallized in the monoclinic space group P21/c, with a = 13.970(11), b = 7.098(6), c = 16.097(12)A, β = 103.910(9)°, Z = 4, V = 1549(2)A3, and R = 0.0768. The crystal structure shows that the complex units are linked by classical intermolecular hydrogen bonds between an uncoordinated carboxyl of one complex molecule and an oxygen atom from a coordinated carboxyl of the adjacent complex molecule to form a single-helical chain. Two infinite homochiral helices self-assemble into a dimer through a non-classical C-H…π hydrogen bonding interaction.
锂与2,2'-(联苯-2,2'-二基双(氧))二乙酸配合物的晶体结构
用x射线衍射法研究了[Li(HL)] (H2L = 2,2′-(联苯-2,2′-二基双(氧))二乙酸)的晶体结构。该配合物在单斜空间群P21/c中结晶,a = 13.970(11), b = 7.098(6), c = 16.097(12) a, β = 103.910(9)°,Z = 4, V = 1549(2)A3, R = 0.0768。晶体结构表明,配合物单元由一个配合物分子的非配位羧基与相邻配合物分子的配位羧基氧原子之间的经典分子间氢键连接而成单螺旋链。两个无限的同手性螺旋通过非经典的C-H…π氢键相互作用自组装成二聚体。
