Template arrangement of {Ni3(μ3-OH)(SO4)(R-NO)2}+ fragments around Na+ cations: An unprecedented {Ni12Na} unit linked by oximate and sulfate bridges

A novel {− Ni12Na2-Ni-}n chain has been characterized from the reaction between 2-pyridylcyanoxime, (pyC{CN}NOH), and nickel(II) sulfate. The template synthesis around a Na+ cation gives an unprecedented arrangement of four nickel triangles coordinated to the central sodium ion by sulfato bridges.
