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 C![[double bond, length as m-dash]](http://www.rsc.org/images/entities/char_e001.gif)
S 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.
