Unprecedented binding and activation of CS2 in a dinuclear copper(i) complex†
Abstract
The first structural characterisation of a copper–carbondisulfide complex revealed a hitherto unknown binding mode for CS2: it interacts with two metal centres (CuI) simultaneously via both CS π bonds. DFT calculations showed that complex formation occurs mainly due to a donation of electron density from the copper centres into the CS π* orbitals.
