    摘要: The title Ni(II) complex, [Ni(C10H26N4)](ClO4)2, crystallizes in yellow and orange forms. In both crystals, the stereochemistry and conformation of the complex cations are identical. Small differences arise from packing effects, differences in the orientations of the perchlorate groups and hydrogen bonding. The Ni(II) atom has square-planar coordination with the four tetraamine N atoms in equatorial positions. In each complex, the two chiral N-atom centres are in the (4RS,7RS) configuration. The tetraamine binds to the Ni(II) atom in a relatively strain-free planar manner; the central six-membered ring exhibits a stable chair conformation and the two terminal five-membered rings adopt stable skew forms.
