A newSeff= 1/2 skew chain compound [Co2(CH3O-ip)(COOH)2(H2O)]nis successfully synthesized by the hydrothermal reaction method. The compound crystallizes in the monoclinic structure with space groupP21/c, in which two inequivalent Co ions, bridged by a μ2-O monodentate formic acid ligand group, form one-dimensional skew chains along thebaxis. The magnetic susceptibility and specific heat data indicate that the compound undergoes two magnetic phase transitions atTN1= 5.8 K andTN2= 6.6 K, respectively. Interestingly, the magnetization curve at 2 K presents a 1/2-like magnetization plateau based on the analysis of Hamiltonian diagonalization.
