摘要：
Crystals of C.I. Disperse Orange 29, a disazo dye, were grown from a methanol solution and the X-ray structure was solved from 2484 independent reflections to R = 0.0497. Results showed that the crystal examined exists in the triclinic space group P1. Interestingly, the structure generated possessed a syn conformation, unlike 4-phenylazoazobenzene which is known to exist in the anti conformation.
