Trend-Analysis of Solid-State Structures: Low-Energy Conformational 'Reactions' Involving Directed and Coupled Movements in Half-Sandwich Compounds [CpFe(CO){C(=O)R}PPh3].

Invited for this month's cover picture are Prof. Dr. Henri Brunner from the University of Regensburg (Germany) and Prof. Dr. Takashi Tsuno from Nihon University (Japan). The cover picture shows the conformational reaction of JIDLUD→FIHTUL. The order of sample points of solid-state structures reveals information concerning low-energy, directed, and coupled movements in molecules.
