  Hydrogen bonded structures in organic amine oxalates

  摘要：

  Oxalates of n-propylamine, n-butylamine, ethylenediamine, 1,4-butanediamine, piperazine, guanidine and 1,4-diazabicyclo[2,2,2]octane (DABCO) have been synthesized and characterized by single crystal X-ray diffraction and other techniques. The amine oxalates show different types of hydrogen bonded networks, linear hydrogen bonded chains characterizing the oxalates of the first five amines. Guanidinium oxalate has a sheet like structure while DABCO oxalate has dimeric hydrogen bonded rings. Hydrogen bonded structures of these oxalates are discussed in detail, besides relating their thermal stability to the strengths of the networks. (C) 2002 Elsevier Science B.V. All rights reserved.

  The structure, synthesis and magnetic properties of three new complex cobalt hydroxyl oxalates are presented, showing a modification of the 2-D double layer hydroxide structure. Co12(OH)18(ox)3(pip) [ox = oxalate, C2O42−; pip = piperazine, C4N2H10] (1), is essentially built from brucite-like layers with a one ninth depletion of the octahedral sites and a preservation of a trigonal crystallographic

• Synthesis of a hierarchy of zinc oxalate structures from amine oxalates

  A hierarchy of novel zinc oxalates including monomers and dimers has been prepared by reaction of amine oxalates with zinc ions, the amine oxalates having been characterized for the first time. In most of the amine oxalates one of the carboxyl groups transfers a proton to the amino nitrogen, leaving the other carboxyl group free to form hydrogen bonds. The zinc oxalates obtained are composed of a network of ZnO6 octahedra and oxalate units, and possess zero-, one-, two- and three-dimensional structures. The monomer, dimer, and chain zinc oxalates are the first members of the hierarchy of structures. Relationships amongst these various oxalate structures are noteworthy and give indications as to the manner in which these structures are formed. Thus, the three-dimensional structure can be formed by the linking of layers, and the layer structure by condensation of linear chains. The isolation and characterization of a hierarchy of zinc oxalates of differing dimensionalities assumes significance in the light of the recent finding that low-dimensional structures transform to higher, more complex structures in the phosphate family.

  通过草酸胺与锌离子的反应制备了一系列新型草酸锌，包括单体和二聚体，首次对草酸胺进行了表征。在大多数胺草酸盐中，一个羧基将质子转移到氨基氮上，使另一个羧基自由形成氢键。所得草酸锌由ZnO6八面体和草酸盐单元网络组成，具有零维、一维、二维和三维结构。单体、二聚体和链状草酸锌是结构层次的第一个成员。这些不同的草酸盐结构之间的关系值得注意，并给出了这些结构形成方式的指示。因此，三维结构可以通过层的连接形成，并且层结构可以通过线性链的缩合形成。鉴于最近发现低维结构转变为磷酸盐家族中更高、更复杂的结构，不同维数的草酸锌层次结构的分离和表征具有重要意义。
