Structural studies on the Bi₂O₃-Nb₂O₅ system (Part I) ; Studies on some novel fluorite-type superstructures (Part II) ; The crystal structure of dicalcium nitride (Part III)

Part I An investigation of some of the crystal structures occurring in the Bi203-Nb205 binary system was undertaken by X-ray methods. The structure of triclinic BiNb04 was solved from visually estimated single-crystal diffraction data. The unit cell has a = 7.611, b = 5.536, c = 7.919 Å, ∝ = 89°54', β = 77°28', γ =87°9', the space group is Pī. The structure, which consists of sheets of niobium-oxygen octahedra linked through bismuth atoms, is of an entirely new type. The mode of joining of the octahedra in the sheets found in this compound is novel. Least-squares refinement with isotropic temperature factors converged to R = 0.122.
