In the structure of the novel zinc complex catena-poly[[diaqua(4-hydroxybenzohydrazide)zinc(II)]-μ-sulfato], [Zn(SO4)(C7H8N2O2)(H2O)2]n, the complex cations are linked by sulfate counter-ions into helical polymeric chains extending along the b axis. Each helix is stabilized by six intrachain hydrogen bonds involving stronger O-H...O (1.83-2.06 Å) and weaker N-H...O (2.20-2.49 Å) interactions. The Zn(II) atom displays a distorted octahedral geometry formed by the 4-hydroxybenzohydrazide ligand, two water molecules and two SO4(2-) ions, which is very similar to the metal-atom environment in a previously reported Co(II) complex [Zasłona, Drożdżewski & Kubiak (2010). J. Mol. Struct. 982, 1-8], especially the Zn-O and Zn-N bond lengths of 2.0453 (12)-2.1602 (9) and 2.1118 (12) Å, respectively.
在新型锌配合物链状聚[[二水合(4-羟基苯甲酰肼)锌(II)]-μ-硫酸根]，即[Zn(SO4)(C7H8N2O2)(H2O)2]n的结构中，配合物阳离子通过硫酸根抗衡离子连接成沿b轴延伸的螺旋状聚合物链。每个螺旋通过六个链内氢键得以稳定，这些氢键涉及较强的O-H...O（1.83 - 2.06 Å）和较弱的N-H...O（2.20 - 2.49 Å）相互作用。Zn(II)原子呈现出由4-羟基苯甲酰肼配体、两个水分子和两个SO4(2-)离子形成的扭曲八面体几何构型，这与先前报道的Co(II)配合物[扎斯洛纳、德罗日杰夫斯基和库比亚克（2010年）。《分子结构杂志》982，1 - 8]中的金属原子环境非常相似，特别是Zn - O和Zn - N键长分别为2.0453(12) - 2.1602(9) Å和2.1118(12) Å。
