One‐Dimensional and Two‐Dimensional Coordination Polymers of Copper(II) Nitrobenzoate with Bridging 3‐Pyridylmethanol Ligand

Abstract

Complexes of composition [Cu(X‐NO2bz)2(μ‐3PM)2]n[X‐NO2bz = 2‐nitrobenzoate (1), 3‐nitrobenzoate (2) or 4‐nitrobenzoate (3) and 3PM = 3‐pyridylmethanol] were prepared and studied by elemental analysis, UV/Vis, IR and EPR spectroscopy. The molecular structures of two new complexes 1 and 3 were solved. The copper atoms of both complexes exhibit an elongated octahedral coordination environment with the equatorial positions occupied by two monodentate nitrobenzoato anions and two 3‐pyridylmethanol nitrogen atoms in trans positions. The both axial positions are occupied by oxygen atoms of bridging 3‐pyridylmetanol ligands The polymeric structure of complex [Cu(2‐NO2bz)2(μ‐3PM)2]n (1) contains two‐dimensional layers. The complex 3 exhibits a polymeric chain‐like structure [Cu(4‐NO2bz)2(μ‐3PM)2]n with copper atoms double‐bridged by two 3‐pyridylmethanol molecules similarly as it was found for complex 2.
