Structural studies on novel Ru(II)–Binap complexes

The solid-state structures for two complexes, 7 and 8, are reported. Complex 7 was prepared by treating Ru(OAc)2(Binap) with two equivalents of HBArF in toluene solution, and represents only the second solid-state structure of a Binap complex, in which the Binap is a 6e donor to the Ru(II). The bonding is maintained in solution as shown via 13C NMR studies. The unusual cation 8, as an SbF6- salt, arises from prolonged reaction of Ru(OAc)2(Binap) with wet HBF4 (and, subsequently, added HSbF6) in 1,2-dichloroethane.

The solid-state structures for the two unusual complexes, 7 and 8, are reported. In 7 the Binap is a six-electron donor. Cation 8 arises from reaction of Ru(OAc)2(Binap) with HBF4 and water.Figure optionsDownload as PowerPoint slide
