Abstract

The monoclinic structure of the dark green title compound, [Ni(hfac)2ΦenΦ], was elucidated employing a PHILIPS PW1100 PC-computer controlled automatic diffractometer using MoKα radiation. The space group is A2/n, Z = 4, and cell dimensions a = 13.932 Å, b = 10.222 Å, c = 19.958 Å, and β = 93.34°. A total of 2105 reflections were measured and the structure was refined by full-matrix least-squares to a conventional R = 0.076 for all observed reflections with I > 2σ(I). The nickel(II) ion is six-coordinated and is positioned at the centre of an almost regular octahedron. The best (equatorial) plane encompasses the nitrogens of the diamine ligand and one carbonyl oxygen atom of each β-dionato metallocyclic ring. The other oxygen donor atoms occupy the remaining apical positions and are equidistant from the metal centre. The Ni – N distances are imperceptibly longer than the Ni – O ones. In the five-membered chelate ring the 1,2-diamine adopts the gauche conformation with the phenyl groups.
