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.
Claims15
A molecular magnetic material comprising salt molecules, the salt molecules comprising:
- a hexsacyanide tungsten anion complex of a formula [WIV(CN)6(NN)]2−,
- a hexsacyanide 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;
- and at least one type of a cation [A]n+, where n is an integer equal from 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+.
