摘　　要：Two novel compounds {[Cu（IBG）（4,4-bipy）（H2O）2]2·11H2O}n（1） and {[Co（IBG）-（μ-H2O）（H2O）2]·2H2O}n（2） based on isophthaloylbisglycine（H2IBG） have been synthesized and structurally characterized by thermogravimetric analysis, elemental analysis and single-crystal X-ray diffraction. Compound 1 shows a 1D chain sine/cosine chain structure, and compound 2 can be characterized as a 4-connected sql tetragonal planar network with the point symbol of {44·62}. Compound 2 has been characterized by magnetic measurements. In addition, 1 and 2 display an interesting reversible crystal-to-amorphous transformation.Two novel compounds {[Cu（IBG）（4,4-bipy）（H2O）2]2·11H2O}n（1） and {[Co（IBG）-（μ-H2O）（H2O）2]·2H2O}n（2） based on isophthaloylbisglycine（H2IBG） have been synthesized and structurally characterized by thermogravimetric analysis, elemental analysis and single-crystal X-ray diffraction.
