The paucity of boron-containing heteroalkene complexes prompted us to explore the coordination of phosphinoboranes. The complexes [R 2PB(C 6F 5) 2]Pt(PPh 3) 2 (R = Cy, t-Bu) were obtained by ethylene displacement. Spectroscopic and crystallographic data indicated symmetric side-on coordination of the phosphinoborane to Pt. Thorough analysis of the bonding situation by computational means revealed important similarities but also significant differences between the phosphinoborane and ethylene complexes. © 2012 American Chemical Society.
