  "abstract": "The pentaPod (pentadentate tetrapodal phosphine) ligand P5R with PMe2 or phospholane (Pln) donors offers the opportunity to investigate how small changes in the ligand framework affect the properties of the corresponding transition-metal complexes. Here, we examine the influence of replacing the propyl with ethyl groups in the trident part of the pentaPod ligand with regard to N2 activation as well as N2-to-NH3 conversion by the corresponding Mo(0)N2 and W(0)N2 complexes. A comparison of the DFT-optimized structures of the original P5R and the shortened etP5R pentaPod complexes reveals important structural differences that influence N2 activation. The geometric and electronic structure results obtained from DFT are checked by comprehensive spectroscopic and electrochemical studies of the new etP5R-supported molybdenum and tungsten systems as well as through an investigation of their ability to (catalytically) generate NH3.",
