Aone-dimensional complex {[Co3(C6(COO)6)(H2O)12]}_6H2O}n has been prepared and its crystal structure determined by X-ray crystallography. In the complex mellitic anion provides its six carboxylate groups to coordinate four cobalt(II) ions, in which a sevenmembered ring was formed by two ortho-carboxylate groups to coordinate the same cobalt( II) ion. Through the four carboxylate groups bridging two cobalt(II) ions the one-dimensional chain structure was formed. The variable-temperature magnetic susceptibility of the complex was measured in the 4-300 K range and the magnetic data indicate the magnetic interaction between the bridged cobalt(II) ions displays an antiferromagnetic coupling.
