Abstract

The elucidation of the crystal structure of one isomer of the mixed metal boride [HFe₄(CO)₁₂{AuPEt₃}₂B] illustrates that the geometry of the hexametal atom core and the location of the endohydrogen atom depend upon the steric, rather than electronic, requirements of the gold(I) phosphine substituents. Electronic effects, however, are responsible for the AuPR₃ fragment interacting with Fe-B rather than Fe-Fe bonds of the core cluster.
