摘要

Three Zn~(II) and Cd~(II) complexes with Y-shaped dicarboxylate ligands, namely [Zn(L_1)(2,2′-bpy)_2(H_2O)]·2H_2O (1), [Zn(L_1)(bpp)(H_2O)] (2), and [Cd(L_1)(H_2O)]·H_2O (3) [H_2L_1 = N-phenyliminodiacetic acid, 2,2′-bpy = 2,2′-bipyridine, bpp = 1,3-bis(4-pyridyl)propane] were synthesized and characterized by elemental analysis, IR spectroscopy single-crystal X-ray diffraction, and thermogravimetric analyses. Compound 1 shows an hydrogen-bonded 2D network, whereas compound 2 is an infinite 1D wavy chain structure, though O–H···O hydrogen-bonded to form a 2D network. Compound 3 displays a 2D uninodal 3-connected Shubnikov plane net with the point symbol of (4.8~2). Moreover, the solid-state such as thermal stabilities and fluorescence properties of 1–3 were also investigated.
