Abstract: cations. The number of nonequivalent halogen sites is two (X1, X2). Short Pb--O bonds are located on one side of the Pb 2+ cations and weak Pb-X bonds are located on the other side of the Pb 2+ coordination sphere. The evident strong distortion of the Pb 2+ coordination polyhedra is due to the stereoactivity of the 6s 2 lone electron pairs of the Pb 2+ cations. Pb1-X2 and Pb2-X2 bonds are the most sensitive to the X site occupancy, which is in agreement with the non-linear behavior of the a and c parameters. D… Show more

“…These chains have been observed previously in crystal structures of natural and synthetic lead oxyhalide compounds (Siidra et al, 2008a). In mendipite (Krivovichev and Burns, 2001;Siidra et al, 2008b), the chains extend along the b axis. They have two mutually perpendicular orientations and are linked through weak PbÀCl bonds only.…”

“…The mixture of α-PbO and SiO 2 was ground in an agate mortar under acetone and after drying loaded into a platinum crucible on the PbCl 2 substrate and kept at 750 °C for 1 h in air, followed by cooling to 25 °C at a cooling rate of 9.5 °C/min. The product consisted of honey-yellow plate crystals of 3 in the mass of Pb 3 O 2 Cl 2 and unidentified amorphous residual. The same mixture cooled down to room temperature at a lower cooling rate of 7 °C/h results in the formation of transparent yellowish crystals of Pb 3 Si 2 O 7 and PbSiO 3 …”

“…What's more, the formed [PbO 3 Cl 4 ], [PbO 4 Cl 4 ] and [PbO 3 Cl 5 ] units in the two compounds are different from the formed [PbO 2 Cl 2 ], [PbO 2 Cl 4 ], [PbO 2 Cl 3 ], [PbOCl 5 ] and [PbO 3 Cl 3 ] mixed anionic groups (Fig. S6†) in Pb 3 O 2 Cl 2 , 42 Pb 17 O 8 Cl 18 , 28 RbPb 8 O 4 Cl 9 43 and Ba 27 Pb 8 O 8 Cl 54 . 44…”
