The structures, physical properties, and reaction chemistry of isoelectronic alkyl complexes of osmium (VI) are compared. The three, five-coordinate alkyl complexes [NBu 4 n ] [Os(N)(CH 2 SiMe 3 ) 4 ], Os(NMe)(CH 2 SiMe 3 ) 4 , and Os(O)(CH 2 SiMe 3 ) 4 have been characterized by single-crystal X-ray diffraction, NMR, IR, UV-visible spectroscopy, and by electrochemical techniques. All have a square-pyramidal
