Hydrothermal synthesis, structure, and magnetic properties of a three-dimensional polymeric Ni-II complex, [Ni(bpp)(NIP)(H2O)](n) (bpp=1,3-di(4-pyridyl)propane, NIP=5-nitroisophthalate)

摘要

A three-dimensional polymeric Ni-II complex, [Ni(bpp)(NIP)(H2O)], (bpp = 1,3-di(4-pyridyl)propane and NIP = 5-nitro-isophthalate), has been synthesized and characterized. The coordination number of the nickel atom is six (NiN2O4) and the coordination environment around the Ni-II atom may be described as a distorted octahedron in which two nitrogen atoms of "bpp" ligand occupy the cis positions. The effective magnetic moment for this complex indicate that the interactions between two Ni-II atoms through the effective exchange media are antiferromagnetic. Self-assembly of these compounds in the solid state via pi-pi-stacking interactions is discussed.
