The chloroform solvent molecules do not participate in non-covalent interactions and therefore, can be found in several positions. The binaphthalene molecules are connected via a system of N-H...O hydrogen bonds between the ureido units. C-H...O interactions also occur. In contrast to unsubstituted urea, where molecules form squares in crystals, the bulky substituents disturb this arrangement and three ureido groups form infinite chains, while the fourth interacts with a neighbouring binaphthalene ring via an N-H interaction. The solvent molecules are disordered with occupancy ratios of 0.60:0.40, 0.58:0.42, 0.50:0.50 and 0.77:0.23.
