 Title    Metal-Mediated Assembly of Hexameric Ethylcycloarsoxane (C2H5AsO)6 in Mono-and Dinuclear Complexes with Tetrahedral and Octahedral Coordination Spheres  
 Abstract    A metal-assisted ring expansion from the preferred solution species (EtAsO),,, n = 3,4, to the hexameric ligand (EtAsO)6 is observed for the reactions of [ReBr(CO)5], [RuCLCPh^P)?], RhCfv3 H2 0 and [C^CCF.^SO.OaCCftHft)] with ethylcycloarsoxane. Whereas two metal frag­ ments are facially coordinated by the upper and lower three As atoms of a flattened AsftOö cuboctahedron in both [{ReBr(CO)2} 2 {M-[cyc/o-(EtAsO)6]}] (1) and [Cu2{n-[cyclo-(EtAs0)6]}(Me2PhP)2](CF3S03)2 (4), potential ring strain restricts the reaction with the other compounds to the formation of mononuclear complexes [RuCl2{cvc/o-(EtAsO)6}(Ph3P)] (2)
