Synthesis, crystal structure and thermal stability of 1D chain manganese coordination polymer

A manganese coordination polymer, [Mn(C7H2I3O2)(2)(CH3OH)(2)](n) was synthesized and characterized by the element analysis, IR, TG and single crystal X-ray diffraction structure analysis.. The title complex crystallizes in monoclinic system with space group P2(1)/c, a=0.461 66(9) nm, b=1.716 6(3) nm, c=1.647 5(3) nm, beta=91.84(3)degrees, and V=1.305 2(4) nm(3), Z=2, R=0.026 2, wR=0.063 4. Each manganese(II) ion exists in an octahedral geometry with four 0 atoms from three different triiodobenzoate groups and two 0 atoms from two methanol molecules. Two adjacent manganese (11) atoms are bridged by two tn*iodobenzoate groups in bis-monodentate mode, constructing a one-dimensional chain structure along a axis, with the adjacent Mn center dot center dot center dot Mn distance being 0.4617(5) nm. Moreover, the weak interactions between the iodine atoms lead to a three-dimensional supramolecular network.
