  text: Seven novel dirhodium coordination polymers (Rh-2-Ln) (n = 1-7) are prepared
    by employing bitopic ligands to connect dirhodium nodes. The formation of the
    framework is confirmed by attenuated total reflectance Fourier transform infrared
    (ATR-FTIR) and H-1 C-13 cross polarization magic angle spinning nuclear magnetic
    resonance (CP MAS NMR) spectroscopy. Defect sites resulting from incomplete ligand
    substitution are revealed by F-19 MAS NMR. The random stacking behavior of the
    frameworks in the obtained solid is analyzed by scanning electron microscopy (SEM)
    and X-ray diffraction (XRD). The Rh-2/O interaction in neighboring layers is investigated
    by diffuse reflectance ultra-violet visible light (DR-UV-vis) spectroscopy and
    X-ray photoelectron spectroscopy (XPS). This interaction is relevant to understand
    the catalytic behavior of various Rh-2-Ln catalysts in the cyclopropanation of
    styrene with ethyl diazoacetate (EDA). In this context, the structure-reactivity
    relationship is discussed by taking into consideration both interlayer Rh-2/O
    interactions and steric effects of side chains.
