摘要
本文介绍了基于分子"[Cu（2、2'-双咪唑)]'模块和丙二酸阴离子自组装合成的四种新型超分子氢键排列的结构表征，即四（2,2'-双咪唑）二-μ-氯基-二马拉三铜（II）五水合物、[Cu3(C3H2O4)2Cl2(C6H6N4)4]-5H2O或[Cu(H2biim)2(μ-Cl)Cu0.5(mal)]2-5H2O，水合(2,2'-联咪唑)丙二酸铜(II)二水合物，[Cu(C3H2O4)(C6H6N4)(H2O)]-2H2O 或 [Cu(H2biim)(mal)(H2O)]-2H2O，双[水合(2,2'-联咪唑)铜(II)]二丙二酸二哌氯铜(II) 2.2-hydrate, [Cu(C6H6N4)2(H2O)]2[Cu(C3H2O4)(ClO4)2]·2.2H2O或[Cu(H2biim)2(H2O)]2[Cu(mal)2(ClO4)2]-2.2H2O，以及双(2,2'-联咪唑)铜(II)双[双(2,2'-联咪唑)(2-羧基乙酰氧基)丙二酸铜(II)]三水合物、[Cu(C6H6N4)2][Cu(C3H2O4)(C3H3O4)(C6H6N4)2]·13H2O or [Cu(H2biim)2][Cu(H2biim)2(Hmal)(mal)]2·13H2O.这些组装体的特点是自互补的供体-受体分子相互作用，显示出配位的 2,2'-联咪唑和丙二酸配体的羧酸基团、羧酸基团和 N-H 基团之间经常出现独特的氢键优先模式。此外，羧酸基团与金属中心的配位有助于将层状、螺旋状、双螺旋柱状或三维通道结构（包括混合金属复合物）等非凡的超分子组装维持在单一结构中。
Multivalent hydrogen-bonded architectures directed by self-complementarity between [Cu(2,2'-biimidazole)] and malonate building blocks.
The synthesis and structural characterization of four novel supramolecular hydrogen-bonded arrangements based on self-assembly from molecular `[Cu(2,2'-biimidazole)]' modules and malonate anions are presented, namely, tetrakis(2,2'-biimidazole)di-μ-chlorido-dimalonatotricopper(II) pentahydrate, [Cu3(C3H2O4)2Cl2(C6H6N4)4]·5H2O or [Cu(H2biim)2(μ-Cl)Cu0.5(mal)]2·5H2O, aqua(2,2'-biimidazole)malonatocopper(II) dihydrate, [Cu(C3H2O4)(C6H6N4)(H2O)]·2H2O or [Cu(H2biim)(mal)(H2O)]·2H2O, bis[aquabis(2,2'-biimidazole)copper(II)] dimalonatodiperchloratocopper(II) 2.2-hydrate, [Cu(C6H6N4)2(H2O)]2[Cu(C3H2O4)(ClO4)2]·2.2H2O or [Cu(H2biim)2(H2O)]2[Cu(mal)2(ClO4)2]·2.2H2O, and bis(2,2'-biimidazole)copper(II) bis[bis(2,2'-biimidazole)(2-carboxyacetato)malonatocopper(II)] tridecahydrate, [Cu(C6H6N4)2][Cu(C3H2O4)(C3H3O4)(C6H6N4)2]·13H2O or [Cu(H2biim)2][Cu(H2biim)2(Hmal)(mal)]2·13H2O. These assemblies are characterized by self-complementary donor-acceptor molecular interactions, demonstrating a recurrent and distinctive pattern of hydrogen-bonding preferences among the carboxylate, carboxylic acid and N-H groups of the coordinated 2,2'-biimidazole and malonate ligands. Additionally, coordination of the carboxylate group with the metallic centre helps sustain remarkable supramolecular assemblies, such as layers, helices, double helix columns or 3D channeled architectures, including mixed-metal complexes, into a single structure.
期刊介绍：
Acta Crystallographica Section C: Structural Chemistry is continuing its transition to a journal that publishes exciting science with structural content, in particular, important results relating to the chemical sciences. Section C is the journal of choice for the rapid publication of articles that highlight interesting research facilitated by the determination, calculation or analysis of structures of any type, other than macromolecular structures. Articles that emphasize the science and the outcomes that were enabled by the study are particularly welcomed. Authors are encouraged to include mainstream science in their papers, thereby producing manuscripts that are substantial scientific well-rounded contributions that appeal to a broad community of readers and increase the profile of the authors.
