Structural diversity of a series of chlorocadmate(II) and chlorocuprate(II) complexes based on benzylamine and its N-methylated derivatives

Protonated benzylamine and its N-methylated derivatives, [C6H5CH2NH3−n(CH3)n]+ (n = 0−3), have been adopted as cations in chlorocadmate(II) and chlorocuprate(II) complexes, showing inorganic–organic hybrid architectures. For the Cd(II) compounds, the anionic structures vary from perovskite-type layers (n = 0) to chains (n = 1–3). For Cu(II) compounds, the anionic structures range from perovskite-type layers (n = 0), chains (n = 1) to mononuclear species (n = 2–3). Coordination geometries of the metal ions and intermolecular interactions have been analyzed. Their dielectric properties have been measured.
