H I total mass in each clusters within 2R200 (red squares) or 2R200 < R < 5R200 (blue solid dots), in comparison with the simulation results from TNG-Cluster (green diamonds D. Nelson et al. 2024) and TNG300 (coral boxes A. Pillepich et al. 2018; D. Nelson et al. 2018; J. P. Naiman et al. 2018; F. Marinacci et al. 2018; V. Springel et al. 2018). H I abundances from SDSS data from A. Obuljen et al. (2019) are shown in black circles.
