J. Zukerman-schpector et al., Adducts of nickel(II) acetylacetonate chelating with heterocyclic bases: 3-cyanopyridine and 4-cyanopyridine, ACT CRYST C, 56, 2000, pp. 763-765
In both title compounds, (acetylacetonato-O,O')bis(3-cyanopyridine-N)nickel
(II), (I), and (acetylacetonato-O,O')bis(4-cyanopyridine-N)nickel(II), (II)
, both [Ni(C5H7O2)(2)- (C6H4N2)(2)],the Ni-II atom, which is situated on a
centre of symmetry, is octahedrally coordinated. Distances and angles for (
I) and (II), respectively, are: Ni-O 2.009 (2)/2.016 (2) and 2.0110 (16)/2.
