Abstract

Experimental X-ray powder diffraction data, unit-cell parameters, and space group for trelagliptin succinate, C18H20FN5O2•C4H6O4, are reported [a = 18.481(6), b = 8.120(4), c = 7.903(4) Å, α = 89.972(0)°, β = 97.722(4)°, γ = 90.120(0)°, unit-cell volume V = 1175.37 Å3, Z = 2, and space-group P1]. All measured lines were indexed and are consistent with the P1 space group. No detectable impurity was observed.
