A new pseudo-two-dimensional niobium chloride selenide, Nb₃Se₁₀Cl₃

J.-E. Kwak, S.-I. Hahn and H. Yun

Abstract: Triniobium decaselenide trichloride, Nb₃Se₁₀Cl₃, contains waved one-dimensional chains in which the Nb atoms are arranged in a sequence of two consecutive short bonds and one long distance. Two Nb atoms are each coordinated by three Se₂^2-, Cl^- and ²-Cl^-, whereas the third Nb atom is surrounded by four Se₂^2- to form distorted rectangular antiprisms of Se. Weak interchain interactions between Se and terminal Cl atoms connect the chains along the [101] direction to form a pseudo-two-dimensional layer. Nb₃Se₁₀Cl₃ is an insulator, in accordance with the charge-balanced formulation [Nb⁵⁺][Nb⁴⁺]₂[Se₂^2-]₅[Cl^-]₃.
