Abstract: The title compound, [Ni(C₁₀H₁₂N₂O)₂(H₂O)₂](BF₄)₂·4C₃H₇NO, was synthesized by the reaction of 2-[3-(dimethylamino)prop-2-enoyl]pyridine and Ni(BF₄)₂ in dimethylformamide. It has been characterized by elemental analysis and X-ray diffraction techniques. The crystal structure reveals that the Ni^II atom, on an inversion center, has an NiN₂O₄ octahedral coordination environment with two carbonyl O atoms and two pyridyl N atoms in the equatorial plane and two water molecules in the axial positions. 2-[3-(Dimethylamino)prop-2-enoyl]pyridine chelates to the Ni atom through the O and pyridine N atoms. Tetrafluoroborate counter-anions and dimethylformamide solvent molecules are not coordinated to the central metal ion.
