摘　　要：Two new cobalt（II） coordination complexes, namely [Co（HL）2（biim）（H2O）2]n·n H2O（1） and [Co（Et L）2（biim）]n·3 n（H2O）·2 n（Et HL）（2）（H2L =（fluorene-9,9-diyl）dipropanoic acid, biim = 1,3-bis（imidazol-1-yl）butane）, have been synthesized using the same starting reactants but different solvent medium. The two complexes exhibit distinctly different structures. Compound 1 exhibits a one-dimensional linear chain structure. However, complex 2 reveals a one-dimensional zigzag chain structure. Thermogravimetric analyses（TGA） and luminescent properties of these two complexes have been discussed.Two new cobalt（II） coordination complexes, namely [Co（HL）2（biim）（H2O）2]n·n H2O（1） and [Co（Et L）2（biim）]n·3 n（H2O）·2 n（Et HL）（2）（H2L =（fluorene-9,9-diyl）dipropanoic acid, biim = 1,3-bis（imidazol-1-yl）butane）, have been synthesized using the same starting reactants but different solvent medium.
