Abstract: The aliphatic Schiff base complex bis(2-imino-4-amino-4-methyl-pentane) nickel(II) nitrate (С₆Н₁₄N₂)₂Ni(KОз)₂ crystallizes in the monoclinic system with the unit cell dimensions a = 9.05, b = 7.36, с = 15.40 Á, ß = 105.4°. The space group symmetry is P2₁/c. The crystal structure of Ni(C₆H₁₄N₂)₂(N0₃)₂ was determined from three-dimensional X-ray data. The square planar coordination of four nitrogen atoms around the nickel(II) atom corresponds to a low-spin (diamagnetic) d⁸ electron configuration of the metal ion. Four nitrogen atoms are at distances of 1.898 (2 x ) and 1.953 Á (2x ).The influence of the electronic structure of the central atom on the molecular structure of the nickel(II) and copper(II) Schiff base complexes is discussed.
