They possessthe following colours: Mn(II) white, Co(II) pink and Cu(II) blue. The carboxylategroups bind as monodentate, or a symmetrical bidentate bridging ligands and tridentate.The thermal stabilities were determined in air at 293-1173K.

The magnetic susceptibilites of the 2,4-dimethoxybenzoates weremeasured over the range 76-303 K and their magnetic moments were calculated.
