On the application of phase relationships to complex structures. XX.<i>RANTAN</i>for large structures and fragment development

Abstract

The RANTAN procedure has been used to solve an unknown structure with 100 atoms in the asymmetric unit. In a test of the power of the method a synthetic structure with 234 atoms in space group P1 was solved without difficulty. RANTAN is also very effective as a multisolution fragment-development procedure with as little as 10% of the structure in the fragment.
