Abstract
A molecular magnetic material comprising salt molecules of a hexsacyanide tungsten anion complex of the formula: [WIV(CN)6(NN)]2-, a hexsacyanide tungsten anion complex of the formula: [WV(CN)6(NN)]—, wherein: W is a tungsten cation, CN is a cyano ligand, and NN is an NN-donating bidentate organic ligand forming a five-membered ring with the tungsten atom; and at least one type of a cation [A]n+¬, where n is an integer in the range of 1 to 4.

A method for preparing a molecular magnetic material, the method comprising the steps of:
- providing a mixture of a hexacyanide tungsten anion complex of a formula [WIV(CN)6(NN)]2- and a hexacyanide tungsten anion complex of a formula [WV(CN)6(NN)]−,
- wherein:
- W is a tungsten cation,
- CN is a cyano ligand, and
- NN is an NN-donating bidentate organic ligand forming a five-membered ring with the tungsten atom;
- adding to said mixture at least one type of a cation [A]n+, where n is an integer equal from 1 to 4, to form salt molecules comprising both anion complexes:
- [WIV(CN)6(NN)]2− and [WV(CN)6(NN)]− and the added cation [A]n+, wherein the cation [A]n+ is selected from the group consisting of Mn2+, Fe2+, Fe3+, Co2+, Ni2+, Ag+, Zn2+, Cd2+, Hg2+, TI2+, Pb2+, Cu2+, Ce3+, Ce4+, Nd3+, La3+, Pr3+, Sm3+, Gd3+, Tb3+, Dy3+, Er3+, Ho3+, Yb3+, Eu3+, H+, Na+, K+, Rb+, Cs+, Pb(bpy)2+, Pb(bpy)22+, Cd(bpy)2+, Cd(bpy)22+, and Zn(bpy)2+.
