Resumen:
We present preliminary results about photometric and spectroscopic properties
of three low X-ray galaxy clusters: RX J0533.8-5746 ([VMF]045, z$\sim$0.29), RX J0533.9-5809 ([VMF98]046, z$\sim$0.198) y RX J1204,3-0350 ([VMF98]113, z$\sim$0.26).
We discuss the Color-Magnitude and Color-Color Diagrams and density maps of these clusters of galaxies.
This study is part of a project to obtain photometric and spectroscopic
properties of low X-ray galaxy clusters in the redshift regime of 0.1 to 0.5.
The main goal is to undertand the role of these intermediate-mass systems in the
morphological evolution of galaxies and how these systems contribute to the
hierarquical structure formation in the Universe.
