This fact is due two mainly factors. The first is about the large variety of structural configurations as staircase ladders linked by briding N-donor ligands or cubane clusters with phospine ligand [1-2] among others. The second is the behaviour of these compounds under external stimuli inducing structural changes on bond distances, dihedral and/or torsional angles and packing between molecules. There are a lot of studies where this external stimuli is the temperature and how it affect the interactions of Cu...Cu. Other similar studies are based on mechanical stimuli as grinding but only a few are using the pressure. We are reporting the structural and luminescence studies under high pressure, at room temperature under high pressure, of three copper iodine samples with different configuration. A cubane cluster type Cu4I4{PPh2(CH2=CH2), 1D coordination polymer (staircase)  CuI(6-methylquinoline) and 2D coordination polymer (staircase). For such compounds we present an analysis about their compressibility and bulk modulus through isothermal Equation of State calculations [3]
