*2.4. Powder X-ray Di*ff*raction*

Powder X-ray diffraction data were collected by means of a Rigaku R-Axis Rapid II diffractometer (XRD Resource Center, St. Petersburg State University) equipped with a rotating anode X-ray source and a curved image plate detector (Debye-Sсherrer geometry, *d* = 127.4 mm, Co*K*α, λ = 1.79021 Å). The data were integrated using the software package Osc2Tab/SQRay [11]. The unit-cell parameters were refined from the powder data using the Pawley method and Topas software [12].
