Abstract: In the adduct bis(1-phenyl-1,3-butanedionate)bis(3-aminopyridine)nickel(II), [Ni(C10H9O2)2(C5H6N2)2], the NiII atom lies on a crystallographic center of symmetry. The coordination geometry around the NiII atom is distorted octahedral. Four O atoms of two 1-phenyl-1,3-butanedionate ligands form the equatorial plane, with Ni-O distances in the range 2.0160 (14)-2.0338 (14) Å. The axial positions are occupied by N atoms of two 3-aminopyridine ligands. The adduct molecules translated by one unit along the a axis are linked by N-HO hydrogen bonds, forming chains.
