The magnesium(II) complex [Mg(DMF)6](BPh4)2 [hexakis(N,N-dimethylformamide-κO)magnesium(II)bis(tetraphenylborate)] was prepared, and characterized by single-crystal X-ray method. The compound crystallized in the orthorhombic space group Fddd and Z = 8 with cell parameters a = 17.107(4)Å, b = 20.585(5)Å, c = 35.776(8)Å, V = 12599(5)Å3. The R1 [I > 2σ(I)] and wR2 (all data) values were 0.0583 and 0.1569, respectively, for all 3621 independent reflections. Six N,N-dimethylformamide (DMF) molecules coordinate to a magnesium(II) ion to form a complex cation, [Mg(DMF)6]2+. Crystallographically, the cation seems to belong to the D2 point group as the result of disorder; however, we have concluded that each cation must belong to the C2 point group based on the DFT computation.
