Notes:
A generalization of the full-symmetry τ translation function [Rius & Miravitlles (1986). Acta Cryst. A42, 402-404] is given that allows the explicit introduction of the positioned part of the structure in its computation. This generalization is useful for the structural expansion of molecular crystals with more than one molecule in the asymmetric unit, specially in those cases where the non-availability of high-resolution diffraction data prevents the use of the tangent-formula recycling of a single positioned fragment, e.g. in the determination of crystal structures from powder diffraction data. Its application to four structures is shown.
