Preparation and X-ray structure of a novel zwitterionic organometallic complex, [ReCu(C2C6F5)2(CO)3(PPh3)2]
Abstract
The reaction between [CuC2C6F5] and [ReCl(CO)3(PPh3)2] affords [ReCu(C2C6F5)2(CO)3(PPh3)2]; an X-ray structure determination shows the complex to be a zwitterionic associate of [Cu(PPh3)]+ and Re(C2C6F5)2 and [Re(C2C6F5)2-(CO)3(PPh3)]– ions, in which Cu–acetylene π-bonding is present.
