• Two halide exchange in copper(II) halide dimers: (4,4′-bipyridinium)Cu2Cl6−xBrx

  The structural and magnetic properties of the series of (4,4′-bipyridinium)Cu2Cl6 − xBrx salts are investigated. All of the compounds are isomorphous, triclinic, space group P1¯. Structurally, the compounds contain pseudo-planar Cu2X62- dimeric species that form stacks due to weak coordination of adjacent dimer anions via semi-coordinate Cu⋯X bonds.

  研究了一系列（4,4'-联吡啶）Cu 2 Cl 6-  x Br x盐的结构和磁性。所有的化合物都是同构的三斜空间群P1 。在结构上，这些化合物包含伪平面Cu2X62-由于相邻二聚阴离子通过半配位Cu⋯X键的弱配位而形成堆栈的二聚体。来自4,4'-联吡啶鎓离子的氢键将电池堆连接在一起成为二维结构框架。次级C–H⋯X氢键迫使相邻层上二聚体之间的X⋯X短接触，X⋯X距离为3.645–3.690Å。以这种方式，预计存在交替交换途径的磁性链：二聚体内交换偶联和X⋯X途径。通过半配位Cu⋯X键在二聚体堆栈中存在一个附加途径，尽管该途径被认为相对较弱，为简单起见而被忽略。磁性研究表明，这些系统表现为具有非常强耦合性的交替AFM链，表明卤化物与卤化物的接触是有效的交换途径。随着溴化物含量的增加，观察到AFM耦合单调增加。Cu2Cl62-的值盐的J 1 / k  = -57.2（6）K和J 2 / k  =
• Halogenido ligand exchange synthesis, spectroscopic properties and thermal behaviour of the inorganic–organic hydrogen-bonded network solid [4,4′-H2bipy][H7O3][RhBr6] containing discrete and weakly associated [H7O3]+ ions

  Dark-red single crystals of 4,4'-bipyridinium triaquahydrogen(l+) hexabromidorhodate(III) [4,4'-H(2)biPy] [H7O3][RhBr6] (1) have been synthesized by a diffusion-controlled ligand exchange process from rhodium(III) chloride trihydrate and 4,4'-bipyridine dissolved in hydrochloric and hydrobromic acid, respectively. 1 could be considered as an inorganic-organic hydrogen-bonded network solid built up from the inorganic isolated hexabromidorhodate [RhBr6](3-) octahedra, organic 4,4'-bipyridinium(2+) [4,4'-H(2)bipy](2+) and triaquahydrogen(1+) [H7O3](+) cations with nearly symmetrical O center dot center dot center dot O distances. The oppositely charged components in the structure of 1 are bound together by an intricate system of weak N(O)-H center dot center dot center dot Br hydrogen bonds. The ATR-FTIR spectrum of 1 confirms the existence of the weakly associated [H3O7](+) cations showing characteristic broad bands at ca. 3380, 1680, 1150 and 600 cm(-1). 1 was found to be a long-time stable at ambient conditions material. It contains a definite amount of acid that is released in a controlled manner - upon heating 1 in a first step releases water forming [4,4'-H(2)bipy] [H5O2][RhBr6] (3) and then, in a second step, [H3O]Br is lost. A comparison of ionic arrangements in the structure of 1 and in 4,4'-bipyridinium dibromide,[4,4'-H(2)bipy]Br-2 (2) shows that both crystal structures contain almost linear rods with alternating inorganic and organic components linked through weak hydrogen bonds.

• Systematics in NH⁺···N-Bonded Monosalts of 4,4′-Bipyridine (44′biPy) with Mineral Acids

  Despite significantly different crystal symmetry and packing, the crystal structures of NH+center dot center dot center dot N hydrogen-bonded salts of 4,4'-bipyridine (44'biPy) with mineral acids HA = HCl, HBr, HI, HClO4, HBF4 and H2SiF6 exhibit close analogies in the hydration, aggregation of the cations and their twisted conformation, as well as proton disordering. All monosalts have been synthesized and, at normal conditions, form crystals of general formula [44'biPyH](+)A(-)center dot xH(2)O (x = 0.5, 1, or 2), and [44'biPyH](2)+SiF62-center dot 5H(2)O. In the structures, the 44'biPyH(+) cations are NH+center dot center dot center dot N bonded into linear chains, and in most [44'biPyH](+)A(-)center dot xH(2)O crystals the protons are disordered, similarly as in anisotropic relaxors 1,4-diazabicyclo[2.2.2]octane hydroiodide and hydrobronnide (dabcoHI and dabcoHBr, respectively). The proton disorder implies generation of point defects of neutral 44'biPy molecules and [44'biPyH(2)](2+) dications in all these structures. In all [44'biPyH](+)A(-) structures investigated, the acid anions are hydrogen bonded to water molecules and interact with pyridine hydrogen atoms. Two polymorphs of [44'biPyH]I-+(-) center dot H2O differ in color: the orthorhombic polymorph alpha is yellow, and the triclinic polymorph beta is orange.

  Three host-guest complexes, (H2O)(2)@(CyH)(2)Q[6]) (4,4'-bpyH)+.Cl-.10H(2)O (1), 1(1,4-dioxane)@m-TriCyHQ[6])(4,4'-bpyH)(+).Cl-.19H(2)O (2), 1(4,4'-bpyH(2))(2+)@TMcQ[6]).2Br(-). 11H(2)O (3), were prepared with three different alkyl substituted cucurbit[6]urils, symmetrical dicyclohexanocucurbit[6]uril (CyH)(2)Q[6]}, meta tricyclohexanocucurbit[6]uril (m-TriCyHQ[6]), symmetrical tetramethylcucurbit[6]uril (TMeQ[6]), and a HCl salt 4,4'-dipyridyl(4,4'-bpyHCl) or a HBr salt 4,4'-dipyridyl[4,4'-bpy(HBr)21 guest. Their crystal structures characterized by single-crystal X-ray diffractions revealed that these hosts can form supramolecular assemblies with the halogen hydride salts of the guest 44bpy through the ion-dipole interaction, hydrogen bonding, C-H center dot center dot center dot pi or N-H center dot center dot center dot pi interaction and pi center dot center dot center dot pi stacking. The substituted alkyl group could affect the interaction model and assembled characteristic of the host and the guest. (C) 2007 Elsevier B.V. All rights reserved.
