3D network Mn-glutarate compound with Mn–O–Mn and Mn–O–C–O–Mn connectivity

The reaction of MnCl2 and glutaric acid in aqueous solution affords a new 3D Mn-glutarate with an empirical formula of Mn3(H2O)[CO2(CH2)3CO2]3 (1). The structure of 1 contains honeycomb-type 12 membered Mn–O–Mn networks of MnO6 octahedra and interconnecting Mn–O–C–O–Mn bridging resulting in magnetic interaction below 3 K.
