' the SQUEEZE removed the contributions of 36 electrons from the reflection file, which corresponds with 36/2 = 18 electrons or 18.0/18 = 1 H2O molecules per asymmetric unit. Since there are two independent molecules in the asymmetric unit, the overall correct formulation for this complex would be C58H39N3-0.5H2O. The contribution of the H2O disordered solvent is removed by the SQUEEZE'
