tris(phosphinoaryl)benzene and stabilized by metal–arene interactions, chloride addition causes reversible NiNi bond cleavage that induces 180° rotation around an aryl–aryl bond (see scheme). A dinickel–chloride moiety was found to rotate around the bridging arene by a mechanism involving breaking and forming NiP bonds.
