A novel one-dimensional chain with nickel(II) macrocyclic complex and extended terephthalato-bridged, namely, [Ni(L)(TPHA)]ź8H2O (1) (L = 1,3,6,9,11,14- hexaaza-tricyclo[12.2.1.16,9]octadecane, TPHA = terephthalate dianion) and a new binuclear Cu(II)-Ni(II) complex, [Cu(oxap)Ni(bpy)2](ClO4)2ź2H2O (2) [oxap = N,N?- bis(2-aminopropyl)oxamido dianion, bpy = 2,2?-bipyridine] have been magnetically characterized by variable-temperature magnetic susceptibilities measurements. The fitting results of the agnetic data of all two complexes support exhibiting the occurrence of an antiferromagnetic coupling with J values of -1.25 cm-1 for 1 and -93.9 cm-1 for 2, respectively.
