Syntheses and structures of the heterometallic clusters [(Ph3PAu)(3)Re(CO)(4)], [(Ph3PAu)(4)Re(CO)(4)](+), [(Ph3PAu)(6)AuRe2(CO)(8)](+), and [(Ph3PAu)(6)Re(CO)(3)](+)

摘要

The reaction of [HRe3(CO)12](2-) with an excess of Ph3PAuCl in CH2Cl2 yields [(Ph3PAu)(4)Re(CO)(4)](+) as the main product, which crystallizes as [(Ph3PAu)(4)Re(CO)(4)]PF6 (.) CH2Cl2 (1 (.) CH2Cl2) after the addition of KPF6.The crystal structure determination reveals a trigonal bipyramidal Au4Re cluster with the Re atom in equatorial position.
