A novel metal hydride cluster anion that catalyzes hydrogenation of nitrogen or hydrogenation of carbon dioxide gas is provided. This metal hydride cluster anion has much higher activity than conventional catalysts. The present invention provides the following formula (1) Or the following formula (2) (Wherein, R may be the same or different and each represents an alkyl group, and X 1 , X 2 and X 3 may be the same or different, respectively, and Ru, Ir, Rh, Represents a metal selected from the group consisting of Os, Fe, Co, Re, Mo, W, Ti, Zr, and Hf, where k is 4, 5, 6, or 7, 1 is 2, 3, 4, or 5, , Which represents an integer determined by the number of electrons of the metal).
