Abstract

Crystals of lead oxychloride Pb13O10Cl6 have been synthesized on the basis of high-temperature solid-state reactions. The Pb13O10Cl6 structure was studied using X-ray single-crystal diffraction analysis. The compound is monoclinic, and the space group is C2/c; the unit-cell dimensions are a = 16.1699(14), b = 7.0086(6), c = 23.578(2) angstrom, beta = 97.75 degrees, and V = 2647.6(4) angstrom(3). The structure has been solved by direct methods and refined to R (1) = 0.0505 for 2671 observed unique reflections. The structure is a 3D framework consisting of OPb4 tetrahedrons. Chlorine atoms are located in the framework channels. The structure contains seven symmetrically independent Pb atoms, which are coordinated by 2 to 4 O2- and 2 to 4 Cl- anions. The synthesized compound is compared with other natural and synthetic lead oxyhalides.
