X-ray powder diffraction studies were performed on {Fe}_3-x{Zn}_x{O}₄ (x=0, 0.0046, 0.0072, 0.015, 0.0185, 0.0249, 0.036) in the temperature range 70 K--300 K. We intended to check if structural characteristics distinguish between the samples exhibiting the Verwey transition of discontinuous and continuous character, as found e.g. for resistivity and heat capacity results. We have found that within experimental error range no clear distinction between those two regimes of the Verwey transition can be deduced from the compositional dependence of lattice constants and monoclinic angle.
