In the title compound, {[CdBr(2)(C(16)H(16)N(2)O(4))]·H(2)O}(n), the Cd(II) ion is six-coordinated by a Br(2)O(4) donor set, with four O atoms from two bridging 1,1'-(butane-1,4-di-yl)bis-(pyridinium-4-carboxyl-ate) ligands. The ligands link the Cd(II) ions into a zigzag chain extending along [0[Formula: see text]1]. O-H⋯O and O-H⋯Br hydrogen bonds involving the uncoordinated water mol-ecules connect the chains.
在标题化合物{[CdBr₂(C₁₆H₁₆N₂O₄)]·H₂O}ₙ中，Cd(II)离子由一个Br₂O₄供体基团六配位，其中四个O原子来自两个桥连的1,1'-（丁烷-1,4-二基）双（吡啶-4-羧酸酯）配体。这些配体将Cd(II)离子连接成沿[01]方向延伸的之字形链。涉及未配位水分子的O—H⋯O和O—H⋯Br氢键连接这些链。
