  We present the X-ray spectral analysis of two complementary sets of
intermediate Seyfert galaxies (ISs). Analyzing X-ray data, we estimate the
hydrogen abundance $N_H$ and test its connection with the [O III] luminosity
acquired from optical observations. The results confirm the conclusions drawn
in a previous study concerning the lack of a direct correlation between the
obscuration measure ($N_H$) and the intrinsic characteristics of the active
nuclei ([O III] luminosity). Instead, we validate the existence of a
correlation between the Seyfert type and the $N_H$ parameter, employing a
separation threshold of approximately 10$^{22}$ atoms cm$^{-2}$.
Simultaneously, our findings align with prior research, corroborating the
relationship between X-ray luminosity and the [O III] luminosity.
