The new synthesis of La2-xAgxCaCu2 O6 was achieved by high-temperature solid-state reaction and the best synthesis conditions were found.The structural studies show that the new compound has the typical crystal structure of La2 12 type compound; La, Ag occupy the 4e position and Ca occupies the 2a position. The relationship between the resistance and the temperature of La1 65Ag0 3 5CaCu2 O6 is manifested as metallic behavior.
