Abstract

The structural, spectroscopic, and thermal properties of monosubstituted Pb(XCH2COO)2 lead acetates (X = Cl (1), Br (2), I (3), and OH (4)) are compared. The crystal structure of 2 is reported for the first time. The structure of 3 is determined at room temperature, while that of 4 is characterized by higher-resolution diffraction data. The Raman and IR spectra of the entire series are recorded and interpreted for the first time; correlations between the nature of the substituent X and the positions of characteristic vibrational bands are revealed. Thermal behavior of the compounds in argon and air is investigated using simultaneous thermal analysis and gas-phase IR spectroscopy. The decomposition products of 1-3 are mixtures of the corresponding lead halide and the halogen-richest lead oxohalide. A topological analysis of the structures of 1-4 demonstrates that the ionic layers in 1-3 are isotypic, in contrast to the structure of 4. When hydrogen bonding is considered, ions in the structure of 4 form a 3-periodic network of a previously unclassified type.
