The 5-chloro-2-methoxybenzoates of Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) were synthesized as solids and their magnetic, spectral and thermal properties studied. The complexes possess colours typical of the M(II) ions. The thermal stabilities were examined in air and nitrogen atmospheres and the products of decompositions were also identified. The magnetic susceptibilities of the complexes were measured over the temperature range 4.4–300 K and the magnetic moments were calculated. The results show that the 5-chloro-2-methoxybenzoates of Mn(II), Co(II) and Ni(II) are octahedral high-spin complexes.
