Abstract

Abstract This study investigated the primary usability of Neumann Kopp’s rule for the reliable prediction of heat capacity values for the alkaline earth boranates. To this end, a comparative analysis of existing literature procedures was conducted, and the most effective approach was implemented. Notably, this study presents the first documented instance of the acquisition of heat capacity data for Be(BH 4 ) 2 and Mg(BH 4 ) 2 at low temperatures.
