| Abstract: | Three ZnII and CdII complexes with Y‐shaped dicarboxylate ligands, namely Zn(L1)(2,2′‐bpy)2(H2O)] · 2H2O ( 1 ), Zn(L1)(bpp)(H2O)] ( 2 ), and Cd(L1)(H2O)] · H2O ( 3 ) H2L1 = 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 (4.82). Moreover, the solid‐state such as thermal stabilities and fluorescence properties of 1 – 3 were also investigated. |
