Abstract
Sessions C605addressed by collecting high quality data at low temperature using a microfocus Cu X-ray source and employing dual-space recycling (SHELXD) for structure solution.The very large numbers of independent molecules present good exercises for the RESI and BLOC commands during refinement.For example, one structure in space group I2 has a unit cell volume of nearly 43 000 Å 3 and contains fourteen independent molecules.Despite a fascinating topological interweaving, more than one-third of the unit cell volume is occupied by solvent molecules that are disordered to the point of being impractical to model.Following application of the SQUEEZE routine in PLATON, the residual R1 decreased from 8.4% to 4.5%.
