Abstract
Two cryostats, a liquid nitrogen gas flow cryostat and a Be walled flow cryostat,
suitable for use on Enraf Nonlus CAD4 four circle diffractometers have been
commissioned and tested. The necessary techniques relating to crystal mounting and
centring tor low-temperature data collection were also developed, The complete
experimental procedure was tested by determining the crystal structures of the following
three compounds at low-temperatures:N-arylpyrrolidin-2-one,4-p-hydroxyphenyl-
9,10,11-trihydroxy-8-ethyl-1,7-dioxaspiro[4,4]-nona-2,6-dione and 5,6-trans-Bromo-
5-hydroxy-3-nitrobicyclo[2,2.2]oct-2-ene.ln performing these structure determinations,
some of the applications of low-temperature crystallography were considered.
