Abstract
Cupric benzoate trihydrate crystallizes in the monoclinic system, space group I2/c, with four formula units in a unit cell of dimensions, a{=}6.98, b{=}34.12, c{=}6.30 Å; β{\doteqdot}90°. There are two kinds of benzoate groups. The carboxyl oxygen atoms of benzoate group I are in direct contacts with copper atoms, while those of group II are coordinated to copper atoms through water molecules. Each copper atom is situated at the center of a deformed octahedron consisted of four water molecules and two oxygen atoms from benzoate group I. The octahedra are linked, by sharing two water molecules, into a column parallel to the c-axis. Within this column, copper atoms lie on a line at an interval of 3.15 Å, which suggests the presence of magnetic anisotropy.
