Abstract
The crystal structures of [CuL](NO3)(ReO4) and [CuL](ReO4)2 (L is 4,6,6-trimethyl-1,9-diamino-3,7-diazanon-3-en) are studied. The square coordination of the copper atom in [CuL](NO3)(ReO4) is completed to a distorted octahedron by two oxygen atoms: Cu…O 2.393 Å and Cu…O 2.685 Å, and that in [CuL](ReO4)2, by Cu…O 2.468 Å and 2.697 Å. The products of thermolysis of the salts in a hydrogen atmosphere at 800°C are mixtures of nanocrystalline metal powders with coherent scattering regions of ~45 nm.
