Tóm tắt

The crystal structure of Mg2P2O7 reported by Lukaszewicz has been refined by least squares analysis. Data of the hkl type with O ≤ k ≤ 6 have been used to obtain improved atomic parameters. The central oxygen atom of the P2O7−4 is found to have enhanced thermal motion in the plane perpendicular to the P—P vector. Thus the P—O—P bond angle appears to be linear in this phase because of a thermal averaging of the position of the central oxygen atom. This conclusion is in agreement with that obtained by Lazarev from infrared studies.
