A stable magnet having a high Tc is provided. The stable magnet is synthesized from an at least one ion of a metal from a metal-containing precursor and molecules of an organic compound in a metal to organic ratio of at least about 1 ion to 1 organic molecule and as much as 10 or more ions to 1 organic molecule. The metal-containing precursor provides at least one ion having a valency lower than its maximum valency state. The organic molecules are selected from a group of organic compounds having a reduction potential suitable to accept at least one electron from the metal ion and an at least one functional group that is able to coordinate with the metal ion.
