a Supramolecular dimer formation of the Rh414 square by the solvophobic effect. b Crystal structure of [Rh414(dmso-S)4]2. Two Rh414 squares engaged each other are shown in red and blue. DMSO molecules axially coordinating to the Rh(II) centers are colored in green. c 1H NMR spectra (500 MHz, 298 K, aromatic region) of (Rh414)2 in CD3NO2/CDCl3 (9:1 (v/v)) and Rh414 in CDCl3. d 1H DOSY spectrum of (Rh414)2 in CD3NO2/CDCl3 (9:1 (v/v)).
