Relations between abundances of the interstellar C₂ molecule and other diatomic species as CH and H₂ are presented based on 33 available sight-lines. Spacial correlations between column densities of diatomic molecules suggest that the C₂ molecule is closely related to interstellar CH with correlation coefficient equal to 0.87±0.05. The column density ratio in the case of C₂ and CH molecules in the ISM is equal to 1.13±0.12.
