摘要: Abstract Crystals of the 2,6-dichlorobenzoyl ester C.I. Disperse Yellow 23 and Orange 29 were grown from chloroform, cell dimensions determined by a least-squares fit. both esters found to exist in monoclinic space group P2 1 /C. The structures these dyes possessed anti conformation, unlike that underivatized 29, but same as reported for 4-phenylazoazobenzene.
