New variant of highly symmetric layered perovskite with coordinated NO3(-) ligand: hydrothermal synthesis, structure, and characterization of Cs2PbCl2(NO3)2.
A new highly symmetric layered lead chloride material, Cs(2)PbCl(2)(NO(3))(2) has been synthesized by a hydrothermal reaction method using Pb(NO(3))(2), CsCl, and water at 240 degrees C. The structure has been determined by single-crystal X-ray diffraction. Cs(2)PbCl(2)(NO(3))(2) has a novel two-dimensional layered structure containing PbO(4)Cl(4) polyhedra and NO(3) trigonal planes. Cs(2)PbCl(2)(NO(3))(2) is a novel variant on the layered perovskite theme, of which the structure is closely related to the n = 1 layered perovskite families. Detailed structural analysis, Infrared and UV-vis diffuse reflectance spectra, thermogravimetric analysis, and ion-exchange reactions of Cs(2)PbCl(2)(NO(3))(2) are reported. Crystal data: Cs(2)PbCl(2)(NO(3))(2), tetragonal, space group I4(1)/amd (No. 141), a = b = 5.6905(6) A, c = 32.946(5) A, V = 1066.9(2) A(3), and Z = 4.
