Crystal Structure and Paramagnetic Properties of [Ni(C₅H₅NO)₆](BrO₃)₂
The compound [Ni(C5H5NO)6](BrO3)2 crystallizes in the space group R3, with the metal atom at the center of the unit cell, which imposes a center of inversion and a threefold rotation axis at the metal atom. The coordination sphere of the nickel is rigorously octahedral; the unit cell parameters are a = 9.513 (1) Å and α = 84.58 (1)°. The analysis of the susceptibilities measured at zero field yields the magnetic parameters g∥ = 2.26 ± 0.02, g⊥ = 2.33 ± 0.02, D/kB = 4.55 ± 0.10 K, and zJ/kB = -0.10 ± 0.05 K. The level-crossing field is found to be 31.0 kOe, and field-induced magnetic ordering in that external field is found not to occur down to at least 500 mK. © 1981 American Chemical Society.
