TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The composition: further comprises at least one polar protic solvent (which is water, ethanol, amine or polyethylene glycol (PEG)), or at least two polar protic solvents (where one of the polar protic solvents is PEG); has a sharp decomposition transition beginning at a temperature of less than or equal to 200 degrees C, preferably less than or equal to 150 degrees C; and comprises at least two metal complexes each comprising a different metal, where the metal complexes are adapted to form a metal alloy upon heating. Preferred Components: The metal complex has a solubility at 25 degrees C of at least 500 mg/ml in the polar protic solvent. The metal complex comprises only one metal. The metal is in an oxidation state of I or II. The metal is silver (preferred), gold, copper, platinum or ruthenium. The first ligand: is a monodentate ligand, a bidentate ligand, or a tridentate ligand; comprises at least two amine groups, which are optionally substituted with a polar group or a linear alkane, preferably unsubstituted amine groups; is ethylenediamine; volatilizes upon heating at a temperature of less than or equal to 200 degrees C, preferably less than or equal to 150 degrees C; and is not ammonia. The second ligand: is a carboxylate (preferred), carboxylate comprising a linear, branched or cyclic alkyl, or is a carboxylate of formula (-O-C(O)-R); is acetate or isobutyrate; and volatilizes upon heating at a temperature of less than or equal to 200 degrees C, preferably less than or equal to 150 degrees C. The metal complex: consists essentially of the metal, the first ligand, and the second ligand; and is a silver containing complex of formula (II).R = less than or equal to 5C alkyl;n = at least 1;R7 = H or linear alkane; andR8 = optionally branched or cyclic alkane.The substrate is an organic substrate, where the ink does not react with the organic substrate. The ink is substantially free of nanoparticles before or after deposition. The metallic conductive film is in the form of a line, or a metal grid comprising repetitively patterned structures forming a grid-like network of vertex-shared polygons and polygon-like structures with a varying number of vertices. Preferred Method: In the method (M1): the depositing step is carried out by inkjet deposition; the reducing step is carried out by heating (at less than or equal to 250 degrees C, preferably less than or equal to 150 degrees C) or irradiating, or at room temperature with a reactive gas; the reducing step comprises at least two heating steps, including a first heating step and a second heating step, where the first heating step is carried out at a first temperature and the second heating step is carried out at a second temperature, the first temperature is lower than the second temperature, and the first and second temperatures are fixed temperatures or a range of temperatures; and the reducing step comprises a first heating step in which the temperature and the time of the heating step is adapted to dry the ink but not to produce a full conversion to a final metallic conductive film. The method (M1) also comprises a third heating step at a third temperature, or consists essentially of only the first and second heating steps, where the first temperature is 75-200 degrees C (preferably 100-160 degrees C), and the second temperature is 200-400 degrees C (preferably 250-350 degrees C). The first heating step is carried out with a first heating time (3-20 minutes) and the second heating step is carried out with a second heating time (30 seconds to 2 minutes), where the first heating time is longer than the second heating time. Preferred Definitions:    R1 = methyl or isopropyl;    R2 = -CH2-CH2- or oxirane-2,3-diyl; and    R3-R6 = H or propyl.    EXAMPLE - 1 g of Silver isobutyrate was placed in a 25 ml one-neck round bottom flask containing a PTFE coated magnetic stir bar. To this, 13 equivalents of ethylene diamine was added. The reaction was proceeded for 2 hours with stirring, then the organics were removed in vacuo to yield ethylenediamine silver isobutyrate as a grey to colorless deliquescent solid. This solid ink precursor was then dissolved in a polar protic solvent (ethanol) in concentrations that ranged up to 500 mg/ml in 100 mg/ml increments to obtain the composition.
