(RPh₃P)[Mn(dca)₃]: A Family of Glass-Forming Hybrid Organic-Inorganic Materials.

ABSTRACT: ABX₃-type hybrid organic-inorganic structures have recently emerged as a new class of meltable materials. Here, by the use of phenylphosphonium derivatives as A cation, we study liquid- and glass-forming behavior of a new family of hybrid structures, (RPh₃P)[Mn(dca)₃] (R = Me, Et, Ph; dca = dicyanamide). These new compounds melt at 196-237 °C (T_m) and then vitrify upon cooling to room temperature, forming glasses. In situ glass formation of this new family of materials was probed on a large scale using a variable-temperature PXRD experiment. Structure analyses of the crystalline and the glasses were carried out by solid-state nuclear magnetic resonance spectroscopy and synchrotron X-ray total scattering techniques for using the pair
