Trend‐Analysis of Solid‐State Structures: Low‐Energy Conformational ‘Reactions’ Involving Directed and Coupled Movements in Half‐Sandwich Compounds [CpFe(CO){C(=O)R}PPh 3 ]

摘要

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. Read the full text of their Communication at 10.1002/open.201800007 . “ Low‐energy directed and coupled movements within half‐sandwich compounds [CpFe(CO){C(=O)R}PPh 3 ] are identified through a trend analysis of their solid‐state structures. The Ph edge and Ph face of the PPh 3 ligand, connected by a weak CH/π interaction, do not move independently but concertedly. Although in the ‘reaction’ JIDLUD→FIHTUL Ph edge rotates counter‐clockwise around the C i ?P bond, Ph face rotates clockwise to maintain the stabilizing CH/π interaction …” Find out more about the story behind the front cover research at 10.1002/open.201800007 .
