摘要

A ternary lanthanum bromide La_3Br_3Ni was synthesized from lanthanum, LaBr_3 and nickel under argon at 800 °C. It crystallizes in the tetragonal space group I4_122 (No. 98) with lattice constants a = 12.1758(9) ? and c = 11.744(2) ?. The structure is derived from the cubic Gd_3I_3C type of space group I4_132 through a tetragonal distortion resulting in a squeezed nickel-centered La_6 octahedron. Electronic structure and bonding of the compound have been investigated.
