Magnetic property and thermal analysis of a Mn(II) complex with [Mn(CO2)]n chains based on 4,4′-bis(1H-imidazol-1-yl-methyl)biphenyl

•Complex 1 exhibits an antiferromagnetic coupling interaction.•Complex 1 includes [Mn(CO2)]n 1D chain and [Mn4(bimb)2(OBA)2(CO2)2]2+ unit.•Complex 1 exhibits solid-state photoluminescence and high thermal stability.

Magnetic coordination polymers have attracted considerable interest due to their novel structures and potential applications. In this paper, one new 2D magnetic manganese coordination polymer {[Mn(bimb)(OBA)]}n (1) was synthesized under solvothermal conditions based on 4,4′-bis(1H-imidazol-1-yl-methyl)biphenyl (bimb) and 4,4′-oxybis(benzoate) (H2OBA). Complex 1 contains [Mn(CO2)]n 1D chains and magnetic susceptibility measurements indicate that compound 1 exhibits an antiferromagnetic coupling interaction. In addition, complex 1 exhibits solid-state photoluminescence and high thermal stability.
