Abstract: A new lanthanum(Ⅲ)-cobalt(Ⅱ) heterometallic polymeric complex of La(Hida)Co(ida)2·0.5H2O(1,ida=iminodiacetate) was hydrothermally synthesized and structurally characterized by the elemental analyses,IR spectrum and the single-crystal X-ray diffraction.The structure of compound 1 consists of one-dimensional lanthanum-cobalt heterometallic chain,which was linked via "linear" tetradentate ida ligands to form the two-dimensional framework.The crystal data for compound 1: monoclinic system,space group(C2/c,) a=0.970 78(19) nm,b=2.412 8(5) nm,c=0.859 64(17) nm,β=114.91(3)°,V=1.826 3(6) nm3,Z=4 and R=0.012 6. Interestingly,the title compound contains ten-coordinate lanthanide(Ⅲ)(ions), which makes it unique as the heteronuclear lanthanide iminoacetate.
