摘要

Three isostructural transition‐metal arsenides and germanides, namely niobium nickel arsenide, Nb 0.92(1) NiAs, niobium cobalt arsenide, NbCoAs, and niobium nickel germanide, NbNiGe, were obtained as inadvertent side products of high‐temperature reactions in sealed niobium containers. In addition to reporting for the very first time the structures of the title compounds, refined from single‐crystal X‐ray diffraction data, this article also serves as a reminder that niobium containers may not be suitable for the synthesis of ternary arsenides and germanides by traditional high‐temperature reactions. Synthetic work involving alkali or alkaline‐earth metals, transition or early post‐transition metals, and elements from groups 14 or 15 under such conditions may yield Nb‐containing products, which at times could be the major products of such reactions.
