title: Unprecedented W2(0) quadruply bonded complex supported by π-donor ligands.
abstract: A quadruply bonded complex W2(DippF)2K2 with a W2(0) core was synthesized and structurally characterized. The observed W-W distance of 2.407(1) Å and DFT calculations are consistent to the unprecedented electronic structure in D(2h) symmetry of σ(2)π(2)π(2)δ(2)δ(2)δ*(2) where the HOMO is the δ* orbital.
