Descripción
Sumario:The title complex, [Ni(C(10)H(10)N(6))(2)][Ni(CN)(4)]·2H(2)O, contains an octa­hedral nickel(II) cation and a square-planar nickel(II) anion. Both the cation and the anion reside on a crystallographic center of inversion. The Ni(II) center in the cation is coordinated by six pyrazol-1-yl rings of two chelating tripyrazol-1-ylmethane [HC(pz)(3)] ligands, with Ni—N distances that range between 2.0647 (19) and 2.0828 (19) Å. The Ni(II) center in the anion is coordinated by four cyanide ligands, with Ni—C distances in the range 1.869 (2)–1.869 (3) Å. The [Ni(CN)(4)](2−) anions are linked by inversion-related water mol­ecules into extended chains that run parallel to the a axis.
