## Abstract It is shown that, in contrast to the 0‐carboxy‐0′‐hydroxy‐azo‐ and ‐azomethine dyestuffs, the 0,0′‐dihydroxy‐azo dyestuffs form exclusively, or at least mainly, sterically homogeneous 1:2‐chromium complexes.

✦ Synopsis
Abstract
N‐(2‐Carboxyphenyl)‐C‐(2‐hydroxy‐1‐naphthyl)‐methylenimine, which is an analogue of (2‐carboxyphenyl)‐azo‐(2‐hydroxy‐1‐naphthalene), is shown to form several isomeric 1:2‐chromium complexes, which are stereoisomers.

## Abstract It has been shown that __o__‐carboxy‐__o__′‐amino‐azo‐dyestuffs analogous to the __o__‐carb‐oxy‐__o__′‐hydroxy‐azo‐dyestuffs form isomeric 1:2‐cobalt complexes which would support the observed rule, which states that stereoisomers are formed only by 6‐6‐ring complexes.
