Abstract
Powder data are given for the chlorine derivatives of two azo pigments, namely 1-(2,5-dichlorophenylazo)-2-hydroxy-3-naphthoic acid 4-chloro-2-methoxyanilide (chlorine derivative of C.I. Pigment Red 9) and 1-(2,5-dichlorophenylazo)-2-hydroxy-3-naphthoic acid 4-chloro-2,5-dimethoxy-anilide (chlorine derivative of C.I. Pigment Brown 1). The patterns have been indexed using single-crystal cell dimensions; the problem of multiple indexing has been reduced by comparison with observed structure factors from single-crystal data.Keywords
