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).
