'the SQUEEZE removed the contributions of 115.0 electrons from the reflection file, which corresponds with 115.0/4 = 28.8 electrons or 28.8/25 = 1.2 C6H14 molecules per asymmetric unit. Since there are two independent molecules in the asymmetric unit, the overall correct formulation for this complex would be C57H48BN-0.6(C6H14).'
