Crystal structure of Tris(ethane-1,2-diamine)nickel(II) diperchlorate monohydrate

Abstract

The crystal structure of the title compound, [Ni(en)₃] (ClO₄)₂,H₂O, has been determined from single-crystal X-ray diffraction data at 295(1) K and refined by least squares to a residual of 0.093 for 1400 'observed' reflections. Crystals are orthorhombic, P bca, a 17.043(7), b 15.922(6), c 13.496(5) Ǻ, Z 8. The precision of the structure determination is adversely affected by very high perchlorate thermal motion. <Ni-N> is 2.13 Ǻ.
