| Abstract: Three 2D sandwich-like layer heterometallic complexes, formulated as [Ln(idaH)M(ida)2]n·0.5nH2O，(H2ida=iminodiacetic acid, Ln=Nd, M=Co (1); Ln=La, M=Co (2); Ln=La, M=Ni (3)) have been synthesized under hydrothermal reaction condition and characterized by X-ray diffraction single-crystal structure analysis, IR spectroscopy, elemental analysis, TGA analysis, XPS techniques and magnetic analysis. The Ln atoms are ten-coordinated and linked up into chains by carboxylic oxygen atoms, which are engrafted by six-coordinated 3d transition metal atoms on both sides to give rise to belt-like chains. The belt-like chains are linked up into 2D network by ida ligands and further extended into 3D open-framework by strong hydrogen-bond interactions. CCDC: 694953, 1; 694954, 2; 694955, 3. |
