Homo-trinuclear [Zn 3 (L)(μ 2 -OAc) 2 (H 2 O)] . CH 2 Cl 2 ( 1 ) and hetero-pentanuclear [Zn 4 (L) 2 Eu(NO 3 ) 3 (H 2 O)] ( 2 ) and [Zn 4 (L) 2 Nd(NO 3 ) 3 (H 2 O)]·CH 3 CH 2 OH ( 3 ) complexes containing a coumarin-skeleton bis(salamo) ligand H 4 L, were successfully prepared and characterized via the means of elemental analyses, single crystal X-ray crystallography, FT-IR, UV–Vis absorption spectroscopy and Hirshfeld surfaces analyses. Complex 1 is a 1:3 ((L) 4− :Zn II ) structure, and complexes 2 and 3 are 2:4:1 ((L) 4− :Zn II :Ln III ) structure. All Zn II atoms in complexes 1 – 3 occupied the N 2 O 2 sites are five-coordinated with geometries of slightly distorted tetragonal pyramid and trigonal bipyramid. Rare earth metal (Eu III and Nd III ) atoms are both coordinated with phenolic oxygen atoms, and eight-coordinated with the square antiprism geometries in complexes 2 and 3 . Water molecules as coordinating solvents participate in the coordination. Supra-molecular structures are built by C H … π and hydrogen bonding interactions in complexes 1 – 3 . Moreover, Hirshfeld surfaces analyses of complexes 1 – 3 were also analysed in detail. Most important of all, luminescences of complexes 1 – 3 were discussed.
