The four different [(Ξ· 6 -arene) and [{Ξ· 6 -(1,4-C 6 H 4 (NH 2 )CH 3 )}Cr(CO) 3 ] were synthesized and structurally characterized by single crystal X-ray diffraction. All compounds form hydrogen bonds in the solid state, leading to dimeric or polymeric networks. The hydrogen bonds are an essential
The complexation of an arene C 6 H 5 X to the tricarbonylchromium unit promotes addition of nucleophiles to the arene ring due to the strong electron-withdrawing ability of the Cr(CO) 3 group. If addition of the nucleophile Nu occurs at the carbon bearing the leaving group X, this is an overall ipso
