Abstract

Two new isomorphous coordination polymers: [M 2(μ-H 2O)(oda) 2(H 2O) 2] n (where M=Mn(II), 1, and M=Cd(II), 2) have been synthesized under hydro(solvo)thermal reaction conditions, which are characterized by single crystal X-ray determination, IR and thermogravimetric analysis (TGA). Both 1 and 2 have a covalently linked one-dimensional chain structure and are self-assembled from the building units M(oda). Magnetic measurement of 1 indicates weak antiferromagnetic interactions along the carboxylate-bridged Mn(II)–Mn(II) chains. Crystallographic data for 1, C 8H 14Mn 2O 13, monoclinic, space group C2/c (no. 15), a=14.831(3) Å, b=7.5388(12) Å, c=13.068(2) Å, β=96.009(2)°, Z=4, V=1453.1(4) A ̊ 3 . Crystallographic data for 2, C 8H 14Cd 2O 13, monoclinic, space group C2/c (no. 15), a=15.0139(3) Å, b=7.5531(3) Å, c=13.3505(5) Å, β=94.333(2)°, Z=4, V=1509.64(9) A ̊ 3 .
