Why is the tantalum bromide cluster the cluster derivative of
choice for phasing large structures? As a inorganic chemist
(in a previous incarnation) I can think of a lot of other
possible clusters that might be suitable. I even have money
from a bioinorganic grant that could finance a PhD student
from October 1st to work on a project with me in Goettingen
to investigate other clusters. In view of the recent
success of Tobias Beck's 'magic triangle' phasing reagent I
think that clusters containing several heavy atoms might well
be worth another look with modern phasing methods (potential
applicants should contact me by email).
