Abstract

As3 makes the connection: [Cp*Mo(CO)2(3-As3)] reacts with Ag[Al{OC(CF3)3}4] to yield a novel dimeric complex featuring the cyclo-As3 ligand in an unusual face-bridging coordination mode. Analytical data and DFT calculations support the existence of a monomer-dimer equilibrium in solution (see scheme). [Cp*Mo(CO)2(3-As3)] also reacts with CuX (X=Cl, Br, I) to yield insoluble dimers consisting of planar Cu2X2 moieties.
