Abstract

Abstract : Mobilization upon cooling Adsorbed on a copper surface, dimolybdenum tetraacetate molecules form an ordered structure of upright‐standing molecules at room temperature. Upon cooling down to 220 K, the molecules become mobile on the surface. This counterintuitive phase transition from an ordered structure at high temperatures to a mobile phase at low temperatures can be explained by a smaller molar entropy in the mobile phase as compared to the ordered phase, as reported by Angelika Kühnle and co‐workers in their Communication on page 19117 .
