Abstract: A nickel m complex Ni (-b shz)2 (DM) (M1 2H 0 with N-0-nitrobenzoylsalicylhydrazide(H-o
nbzshz )and monodentate N-donor heterocycle, morpholine (Mn)has been synthesized and characterized by
elemental analysis, IR, TGA and single-crystal X-ray diffraction. The complex reveals a centrosymmetric
trinuclear structure, in which the three nickel(D) centers are bridged by two N-N single bridges. The Nil. Ni2
separation is 0.458 6(1 )nm. The central nickel atom adopts an ax ally elongated octahedral geometry whereas the
nickel atoms on the two sides have square-planar coordination eometry. The complex forms an infinite 2D
network structure by intermolecular hydrogen bonds. The magnetic property has been investigated by variable
temperature magnetic susceptibility measurement. CCDC: 954042
