2-Bromoleptoclinidinone methanol solvate, C18H8BrN3O·CH4O, crystallizes in the orthorhombic space group Pbca with a = 15.7013(2), b = 7.3308(1), and c = 26.9326(1) Å. The molecule is essentially planar, with the largest deviations occurring at bromine (-0.21 Å), carbonyl oxygen O(l) (+0.19 Å) and in ring-A (C(9) -0.15 Å, C(10) -0.15 Å). Methanol occupies the 1,10-phenanthroline-like metal binding site of the title compound.
