title: Novel 3-D framework nickel(II) complex with azide, nicotinic acid, and nicotinate(1-) as coligands: hydrothermal synthesis, structure, and magnetic properties.
abstract: The hydrothermal reaction of Ni(NO3)2, NaN3, and nicotinic acid (Hnic) yielded a 3-D supramolecular framework complex, [Ni(1.5)(N3)(nic)2(Hnic)]n (1) with unusual magnetic properties. In 1, Hnic and nic-1 coexist and show different coordination modes (mu2-Hnic-N,O, mu2-nic-N,O, and mu3-nic-N,O,O bridging NiII ions), and azide groups adopt mu-1,1 (EO) bridging mode linking NiII ions with an unusual Ni-N-Ni angle.
