A new dinuclear hydrated zinc (II) tartrate complex has been successfully synthesized via a solid-state reaction at low temperature under the presence of polyethylene glycol 400 as a structure-directed agent and structurally characterized by single-crystal X-ray diffraction, and further identified by element analyses, FT-IR spectra and TG/DTA measurements. It formulates as [Zn4(C4H4O6)4(H2O)8]·(H2O)12 and crystallizes in monoclinic system, and the space group is P2 (1)/c with cell parameters a = 13.681(3), b = 17.059(3), c = 18.483(4) Å, β = 96.62(3)°, and Z = 4. The structure of the title complex consists of two crystallographic independent dimeric units of [Zn2(C4H4O6)2(H2O)4], 12 lattice water molecules. In each dimeric unit, two tartrate dianions bridges the two Zn (II) ions by using one hydroxy oxygen and one carboxy oxygen atoms as donor atoms, respectively. Each Zinc atom is six-coordinated by four oxygen atoms from two tartrate dianions and two oxygen atoms from the water molecules.Graphical AbstractA new dinuclear hydrated zinc (II) tartrate complex has been successfully synthesized via a solid-state reaction at low temperature and structurally characterized by single crystal X-ray diffraction, element analysis, FT-IR and TG/DTA measurements. The figure shows the ORTEP diagram of the title complex.

水合酒石酸锌 (II) 配合物的固态合成和结构表征

在聚乙二醇400作为结构导向剂存在下，通过低温固相反应成功合成了一种新的双核水合酒石酸锌（II）配合物，并通过单晶X射线衍射进行了结构表征，并进一步通过元素分析、FT-IR 光谱和 TG/DTA 测量确定。公式为[Zn4(C4H4O6)4(H2O)8]·(H2O)12，结晶为单斜晶系，空间群为P2(1)/c，晶胞参数a = 13.681(3), b = 17.059( 3), c = 18.483(4) Å, β = 96.62(3)°, and Z = 4. 标题复合物的结构由 [Zn2(C4H4O6)2(H2O)4] 的两个晶体学独立二聚单元组成， 12个晶格水分子。在每个二聚体单元中，两个酒石酸二价阴离子分别使用一个羟基氧和一个羧基氧原子作为供体原子，桥接两个 Zn (II) 离子。每个锌原子由来自两个酒石酸二价阴离子的四个氧原子和来自水分子的两个氧原子进行六配位。通过单晶 X 射线衍射、元素分析、FT-IR 和 TG/DTA 测量表征。该图显示了标题复合体的 ORTEP 图。图形摘要通过低温固相反应成功合成了一种新的双核水合酒石酸锌 (II) 配合物，并通过单晶 X 射线衍射、元素分析、FT-IR 和 TG/DTA 测量对其进行了结构表征。该图显示了标题复合体的 ORTEP 图。图形摘要通过低温固相反应成功合成了一种新的双核水合酒石酸锌 (II) 配合物，并通过单晶 X 射线衍射、元素分析、FT-IR 和 TG/DTA 测量对其进行了结构表征。该图显示了标题复合体的 ORTEP 图。
