Isolation and characterisation of a novel thermally stable octahedral bicarbonato complex of bis(2-picolylamine)copper(ii): identification of rare monodentate coordination

Abstract

A novel bicarbonate complex, [Cu(C₅H₄NCH₂NH₂)₂(OCO₂H)₂] (1), has been synthesised under controlled pH and characterised by IR, UV-Vis spectroscopy, magnetic moment and thermal analysis; the coordination environment around the metal centre is elongated octahedral with two chelated bidentate amines in the square plane and the axial sites are occupied by two monodentate bicarbonate ligands.
