On the basis of the novel heterocyclic β-diketone, 4-sebacoylbis(1-phenyl-3-methyl-5-pyrazolone (H 2 SbBP), three new lanthanide complexes Tb 2 (SbBP) 3 (H 2 O) 2 (1), Gd 2 (SbBP) 3 (H 2 O) 2 (2), and [Tb(SbBP) 2 ] [Na(DB18C6)H 2 O] (3) have been synthesized and characterized by various spectroscopic techniques. The single-crystal X-ray diffraction analysis of 3 reveals that the complex crystallizes in the monoclinic space group C2/c with a = 25.300(6) Å, b = 19.204(7) Å, c = 15.391(3) Å, β = 93.17(3)°, and V = 7466(4) Å 3 . The crystal structure of 3 is heterodinuclear and features a Tb 3+ center surrounded by two tetradentate bispyrazolone ligands in a somewhat distorted square-antiprismatic geometry. The Na + coordination environment is distorted hexagonal pyramidal and involves six oxygen atoms furnished by DB18C6 and one oxygen atom from a water molecule. The X-ray diffraction study of 3 also revealed an interesting 1D molecular ladder structure based on C-H/π, intra- and i
