چکیده
In the title compound, C(28)H(18)O(4)·2C(3)H(7)NO, the dihedral angle between the benzene rings and the anthracene system is 74.05 (12)°. A crystallographic inversion centre is located in the middle of the anthracene unit. The dimethyl-formamide solvent mol-ecules are partially disordered over two positions of approximately equal occupancy [0.529 (6):0.471 (6)]. Inter-molecular O-H⋯O hydrogen bonds with the major occupancy formamide O atom as acceptor result in the formation of 2:1 solvate-complex aggregates, which are alternately linked to shorter solvate units via weak inter-molecular C-H⋯O contacts generated from the rotational disorder of the formamide O atom (minor occupancy component). Weak C-H⋯π inter-actions between the solvent mol-ecules as the donor and the outer anthracene rings support these contacts in the crystal structure for both disorder components.
