We have designed a family of complexes by coordination of hydrocarbon radicals to group 6 transition metals,which are M(OMe)3η3-C4H5,M(OMe)3η3-C6H7,M(OMe)3η3-C8H7,M(OMe)3η3-C9H5,M(OMe)3η3-C12H9,M(OMe)3η3-C13H7,and M(OMe)3η3-C15H7(M=Cr,Mo,and W).Using density functional theory(DFT),the structures,stability,Wiberg bond indices(WBIs)and aromaticity of these complexes have been investigated.Calculated results indicated each complex contains a planar tetracoordinate carbon(ptC)arising from the formation of 1,3-metal-carbon bond.
