Abstract

A calibration procedure for the three-circle goniometer/2D detector system is described. It is based on the construction of calibration graphs Δ2θ(2θ) from the results of processing Kα₁ and Kα₂ components of external reference reflections successively brought to the equatorial circumference. A Si single crystal is used as the reference. Random errors are estimated. Results of the refinement of unit cell parameters of [Pt(NH₃)₄]MO₄ (М = Cr, Mo, W) are compared by several procedures, including the obtained calibration. The relative error of the performed measurements does not exceed 2·10^–4.
