[6,13-Bis(2,4-dichloro­benzo­yl)-5,7,12,14-tetra­methyl­dibenzo[b,i][1,4,8,11]tetra­aza­cyclo­tetra­decinato- κ⁴N]nickel(II) acetone monosolvate

In the title complex, [Ni(C₃₆H₂₆Cl₄N₄O₂)]·C₃H₆O, two 2,4-dichloro­benzoyl groups are grafted onto the methine groups of the Ni^II complex Ni(tmtaa) (H₂tmtaa = 5,7,12,14-tetra­methyl-4,11-dihydro­dibenzo[b,i][1,4,8,11]tetra­aza­cyclo­tetra­decine). The complex has the shape of a saddle. The Ni atom is tetra­coordinated by the four N atoms of the macrocycle, forming a slightly tetra­hedrally distorted square-planar geometry. The metal is displaced by 0.0101 (8) Å from the N₄ mean plane. The aromatic rings of the 2,4-dichloro­benzoyl groups form dihedral angles of 87.1 (2) and 82.1 (2)° with the N₄ mean plane
