Abstract
A new 2D polymeric Mn(II) has been prepared by self-assembly of manganese acetate with oxalic acid and 2-amino-4-picolineand elucidated through single-crystal X-ray diffraction. The complex (C6H9N2)2[Mn(C2O4)2].H2O was considered as a single-chain magnet based on the oxalate linker, intercalated by [C6H9N2]2+ organic cations and one crystallization water molecule that are entrapped between the layers. The Mn(II) ion is coordinated in a slightly distorted octahedral environment by six oxygen atoms belonging to three chelating oxalates. Thermal analysis, FTIR and UV–Vis diffuse reflectance spectroscopy from which the optical properties were determined. The described complex gave antibacterial activity especially against gram-positive bacteria tested species, antifungal activity against Candida albicans specie, as well as lysozyme and anti-biofilm activities.
