报道了三种卤代吡啶卤代金属盐的合成和晶体结构。（4-ClpyH）2[PdCl4]
(1)和（4-ClpyH）2[Cu 3Cl 8]
(2)采用非常类似于一系列氢键结构的带状结构，所述氢键结构包含二价阳离子如4，4-联吡啶或它们的超分子类似物。这需要阳离子之间通过对称的C-Cl → Cl-C排列进行短暂的相互作用，这种排列很可能是排斥性的。第三种化合物，（4-BrpyH）2[PtCl 6]
(3)形成了三维网络结构，不仅包含分叉的N-H [Cl（Pt）]2氢键，还包含不常见的分叉的C-Br [Cl（Pt）]2卤键。这组结构为已建立的氢键卤代金属酸盐同源系列提供了意想不到的扩展。
The synthesis and crystal structures of three halopyridinium halometallate salts are reported. (4-ClpyH)2[PdCl4]
(1) and (4-ClpyH)2[Cu3Cl8]
(2) adopt tape structures closely resembling a series of hydrogen-bonded structures that contain either dications such as 4,4-bipyridinium or their supramolecular analogues. This requires a short interaction between cations via a symmetric C–Cl⋯Cl–C arrangement that is most probably repulsive. The third compound, (4-BrpyH)2[PtCl6]
(3), forms a 3-D network structure that involves not only bifurcated N–H⋯[Cl(Pt)]2 hydrogen bonds but also uncommon bifurcated C–Br⋯[Cl(Pt)]2 halogen bonds. This set of structures provides unanticipated extensions to established homologous series of hydrogen-bonded halometallate salts.
