A novel compound which is used as an organic metal complex for metal pastes and the like, is free from sulfur and chlorine, and hence can contribute to the purification of the environment; and a process for preparing the same. Specifically a metal acetylide compound represented by the general formula M(-CC-R)n, wherein M represents a metal atom; n represents the valency of the metal atom M; and R represents a hydrocarbon group having one to eight carbon atoms and optionally containing an oxygen atom. As this compound contains neither sulfur non chlorine, it emits neither sulfur dioxide gas nor chlorine compounds, when used for metal pastes and the like, thus contributing to the purification of the environment. Use of a solid sulfite as a metal reducing agent facilitates stoichiometrical control of the reaction and preparation of a metal acetylide compound. Further, since this process does not evolve sulfur dioxide gas, it is free from the fear of environmental pollution and can contribute to the purification of the environment. |
