The growth and structures of three new cocrystals-C9Cl 6Br3N·C60, C9Cl 6Br3N·C70, and C9Cl 6H3N·3C70·3C6H 5Cl-involving fullerenes and halogenated azatriquinacenes are reported. In each case, the fullerene is completely ordered and avoids the orientational disorder found in many crystalline fullerenes and fullerene cocrystals. In each structure, the upper Cl6 surface of the halogenated azatriquinacene molecule cups a fullerene. In C9Cl 6Br3N-C60 and C9Cl 6Br3N·C70, the molecules are arranged alternately in columns with the lower Br3 face of the azatriquinacene also interacting with a neighboring fullerene. In C9H 3Cl6N·3C70·3C6H 5Cl, one of the fullerenes is cupped by the upper surface of the azatriquinacene, while four chlorobenzene molecules also form a belt around it.
