Bis[hexa-amminecobalt(III)] penta-chloride nitrate.
The title compound, [Co(NH(3))(6)](2)Cl(5)(NO(3)), was obtained under hydro-thermal conditions. The asymmetric unit contains three Co(3+) ions, one lying on an inversion center and the other two located at 2/m positions. All Co(3+) ions are six-coordinated by NH(3) mol-ecules, forming [Co(NH(3))(6)](3+) octahedra, with Co-N distances in the range 1.945 (4)-1.967 (3) Å. The nitrate N atom and one of the O atoms lie at a mirror plane. Among the Cl(-) anions, one lies in a general position, one on a twofold axis and two on a mirror plane. N-H⋯O and N-H⋯Cl hydrogen bonds link the cations and anions into a three-dimensional network.
