Metal Halide Ammines. III. Thermal Analyses and Calorimetry of Fluorosilicate Ammines and Hydrates of Bivalent Metals. Infrared Spectra of the Ammines

Abstract

Bivalent metal fluorosilicate ammines have been prepared. The thermal analyses of the dodecammines reveal the decomposition to occur via the pentammine and/or tetrammine. The final ammonia loss is concomitant with fluorosilicate decomposition. Calorimetric data are given for the decomposition reactions. Some fluorosilicate hydrates are included for comparison purposes.The infrared spectral data of the ammines are presented with their assignments.
