Their formulas are presented as following:( 1 ) [Co2C6H2(COO44]n ( 2 ){[Co2(C2O4)C6H2(COO4(H2O)4] -4H2O-(NH2CH2COOH)}n ( 3 ){[Co(H2O)6][Co(H2O)4C6H2(COO4] . 4H2O}n These coordination polymers have been characterized by IR,UV-VIS-NIR spectroscopes. The variable temperature magnetic susceptibilities(1.5-300K)of complex (1) and (2) have been measured and studied. Complex (1) and (2) exhibit the anti-ferromagnetic property. The spin-transition phenomenon of complex (2) takes place at 17K.

经X-光衍射测定，确定了它们的结构，分子式如下：(1)[Co_2C_6H_2(COO_4_4]_n (2){[Co_2(C_2O_4)C_6H_2(COO_4(H_2O)_4]·4H_2O·(NH_2CH_2COOH)}_n (3){[Co(H_2O)_6][Co(H_2O)_4C_6H_2(COO_4]·4H_2O}_n 研究了上述三种配位聚合物的红外，紫外—可见—近红外光谱，测定了化合物(1)和(2)在1.5—300K温度范围内的变温磁矩，对它们的磁性研究表明，化合物(1)和(2)均呈反铁磁性，并且化合物(2)在17K发生了自旋转换现象。
