TECHNOLOGY FOCUS - IMAGING AND COMMUNICATION - Preferred Composition: The ink is free of nanoparticles before or after deposition. Preferred Method: The producing step is carried out by heating at 200 degrees C or less (preferably 150 degrees C or less) or irradiating. The film is in the form of a line, and the line has a conductivity of at least 1000 (preferably at least 10000) S/cm. The line has a work function, which is within 25% (preferably 5%) of the work function of the pure metal. The step of depositing the ink forms a deposit, which is converted to the metal film exhibiting a work function within 25% of the work function of the pure metal. The deposit is heated or irradiated. The step of depositing is carried out by inkjet deposition. The step of conversion is carried out by heating at 250 degrees C or less (preferably 150 degrees C or less).    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The composition is substantially or totally free of nanoparticles. The composition has a sharp decomposition transition beginning at a temperature of less than 200 degrees C (preferably less than 150 degrees C). The composition can be stored at 25 degrees C for at least 100 hours without substantial deposition of metal (0). The composition further comprises: at least one solvent (preferably at least one aromatic hydrocarbon solvent), where the concentration of the solvent in the complex is 200 mg/ml or less. Preferred Components: The metal is silver, gold, copper, platinum or ruthenium. The metal complex comprises only one metal center. The metal is in an oxidation state of (I) or (II). The first ligand is a monodentate-, bidentate- or tridentate-ligand. The metal complex comprises at least 25 (preferably at least 70) wt.% of metal. The content of metal in the complex is at least 50 wt.%. The metal complex is heated to 150 degrees C or less. The composition upon heating provides: a metal with a work function of within 25% of the work function of the pure metal; and provides a metal composition having a conductivity of at least 1000 S/cm.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The first ligand is: an amine compound comprising at least two nitrogens; an unsymmetrical amine compound comprising at least two nitrogens; an amine; a sulfur-containing ligand; a thioether; or not a phosphine. The second ligand is a carboxylate comprising an alkyl group, where the carboxylate is of formula (OOC-R). The second ligand is a carboxylate, and the first ligand is a polydentate unsymmetrical amine, the metal is silver, gold (both preferred) or copper and the solvent is toluene or xylene. When at least one first ligand is a sulfur-containing ligand then the second ligand is optionally a carboxylate. The first ligand is a sulfur-containing ligand, which includes a cyclic or linear thioether ligand (preferably cyclic thioether), dialkythioether, dithiaalkane, dithioctane, tetrahydrothiophene or thioether. The sulfur-containing ligand: comprises one or two sulfur atoms; is a bidentate ligand; and has 6 carbons or less. The first ligand is a neutral sigma donor and volatilizes upon heating the metal complex to a temperature below 150 degrees C and the second anionic ligand also volatilizes upon heating the metal complex to a temperature below 150 degrees C. The first ligand comprises: at least two sulfurs; and six or fewer (preferably two or fewer) carbon atoms. The number of carbon atoms in the complex is 12 or less. When the first and second ligands are same, the first ligand comprises at least one nitrogen atom, at least two oxygen atoms, and at least one fluorine. The first ligand is a tridentate ligand (preferably a tridentate Schiff base ligand). The first ligand comprises at least one secondary amine group, at least one carbonyl group and at least one ether group. The first ligand consists essentially of nitrogen and/or sulfur, the second ligand consists essentially of a carboxylate and the complex is soluble in toluene. The complex consists of the metal, the first ligand and the second ligand, which is neutrally charged.R = an alkyl group having 5 or fewer carbon atoms. EXAMPLE - No suitable example given.
