Solvothermal synthesis and characterization of tris(ethylenediamine)nickel(II) hexaselenodistannate(IV) (original) (raw)

The title compound, [Ni(C 2 H 8 N 2) 3 ] 2 [Sn 2 Se 6 ], was synthesized under solvothermal conditions in an ethylenediamine/water solution at 453 K. The compound contains discrete centrosymmetric [Sn 2 Se 6 ] 4À anions, which are dimers of two tetrahedral SnSe 4 groups sharing a common edge. The transition metal cation is six-coordinated by three ethylenediamine molecules in an octahedral geometry.
