PURPOSE:To obtain the titled complex useful as a raw material for a transition metal chalcogenide of the former period which is an inorganic high polymer having improved physical properties, by reacting a halide, e.g. Nb, Zr, etc., with lithium polysulfide. CONSTITUTION:This invention provides a transition metal polysulfide complex of the former period expressed by table I. This complex, particularly the transition metal polysulfide complex of the former period expressed by formula II (A is Li) is obtained by reacting a metal halide expressed by formula III with a lithium polysulfide expressed by formula IV. Li[Nb3S12], etc., may be cited as the complex expressed by said formula I. For example, NbC3 is cited as the metal halide expressed by formula III and, e.g. Li2S, is cited as the lithium polysulfide expressed by formula IV. According to this invention, the high-purity transition metal polysulfide complex of the former period is obtained in high yield and is capable of being an inorganic high polymer, e.g. niobium chalcogenide, etc., having good electric conductivity by simple thermal decomposition reaction.
