    "abstract": "Phase transitions (liquid-solid, solid-solid) triggered by temperature\nchanges are studied in free nanosized clusters of TeF_6 (SF_6) with different\nnegative charges assigned to the fluorine atoms. Molecular dynamics simulations\nat constant energy show that the charge increase from q_F=0.1 e to q_F=0.25 e\nshifts the melting temperature towards higher values and some of the metastable\nsolid states disappear. The increased repulsive interaction maintains the order\nin molecular systems at higher temperatures.",
