Synthesis, Crystal Structure and Magnetic Property of Trinuclear Nickel(II) Complex Based on N-o-Nitrobenzoylsalicylhydrazide and Morpholine Ligands

A nickel (II) complex [Ni-3(o-nbzshz)(2)(DMF)(2)(Mf)(2)]center dot 2H(2)O with N-o-nitrobenzoylsalicylhydrazide (H-3-o-nbzshz) and monodentate N-donor heterocycle, morpholine (Mf) 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(I) centers are bridged by two N-N single bridges. The Ni1 center dot center dot center dot Ni2 separation is 0.458 6(1) nm. The central nickel atom adopts an axially elongated octahedral geometry whereas the nickel atoms on the two sides have square-planar coordination geometry. The complex forms an infinite 2D network structure by intermolecular hydrogen bonds. The magnetic property has been investigated by variable temperature magnetic susceptibility measurement.
