Tris(3,3′-diamino-2,2′-bipyridine)cadmium(II) dinitrate

Abstract

In the title compound, [Cd(C10H10N4)3](NO3)2, the CdII atom lies on the inter­section of a threefold axis and three twofold axes, and is coordinated by the six N atoms from the three 3,3′-diamino-2,2′-bipyridine ligands, with a Cd—N distance of 2.328 (2) Å. The crystal packing is stabilized by inter­molecular N—H⋯O hydrogen bonds between the amino groups and nitrate anions.
