Abstract	The title compound, [Ni(CH 3 CN) 2 ((CH 3 ) 2 NCOCH 3 } 4 ]-(BF 4 ) 2 , has an octahedral coordination structure with the centre of symmetry at the Ni atom. Both of the two crystallographically inequivalent N,N-dimethylacetamide (DMA) molecules have normal coordination Ni-O bond lengths and Ni-O-C angles, but one of the Ni-OR-N torsion angles deviates from 180°, indicating that the Ni-O bond is displaced from the direction of the lone pair of the sp 2 -O atom. This is ascribed to the steric hindrance of DMA coordination in an octahedral environment, which is imposed by the non-bonding contact of the acetyl methyl group with the ligating O atom of the adjacent DMA molecule.
