空间群P21/a，每个细胞两个分子。通过对x射线衍射数据的三维傅里叶和最小二乘改进确定了原子位置。锌离子位于体系中心，周围是由水分子（Zn-H20 2- 12a_和2.07~ k）组成的稍微扭曲的八面体，硫酸盐离子（so1.48 a, oso109”4）通过一系列长度从2.72 A_到2-85 i不等的氢键与六水锌离子的水分子相连。
space group P21/a, two molecules per unit cell. The atomic positions have been determined by three-dimensional Fourier and least-squares refinement of X-ray diffraction data. The zinc ion lies at a centre of syrm~ etry surrounded by a slightly distorted octahedron of water molecules,(Zn-H20 2-12 A_ and 2.07~ k) and the sulfate ion (SO 1.48 A, OSO 109" 4) is bonded to the water molecules of the hexa-aquozinc ion by a series of hydrogen bonds varying in length from 2.72 A_ to 2-85 i.
