A tetranuclear metallarectangle ( 2 ) derived from dinuclear rhodium(III) building block [Cp* 2 Rh 2 ( μ ‐η 2 ‐η 2 ‐C 2 O 4 )]Cl 2 and imidazole‐based perylene bisimide ditopic ligand ( 1 ) ( 1= 2,9‐bis(4‐(1 H ‐imidazol‐1‐yl)phenyl)‐5,6,12,13‐tetrachloroanthra‐[2,1,9‐ def :6,5,10‐d′e′f′]diisoquinoline‐1,3,8,10(2 H ,9 H )‐tetraone) in presence of silver triflate is reported. The self‐assembled metallarectangle 2 is fully characterized by NMR, ESI‐MS, UV‐vis absorption, fluorescence emission spectroscopy and cyclic voltammetry. The X‐ray diffraction analysis reveals a twisted conformational geometry of metallarectangle 2 caused by essential steric demands of the two side‐by‐side chlorine atoms. In addition, the analyzed structure also elaborates the intermolecular electrostatic interactions between the electron‐deficient diimide moiety of 2 and the electron‐rich planar phenanthrene molecule.
