Its asymmetric unit consists of two crystallographically independent copper(I) cations and cyanide anions as well as one crystallographically independent 2,6-dimethylpyrazine ligand in general positions. Each copper cation is fourfold coordinated by one N atom of the 2,6-dimethylpyrazine ligand and three cyanide anions, that are disordered so that each C and N position has mixed occupancy with a ratio between N and C of 94:6 and 77:23. The copper cations are linked by the cyanide atoms into layers that are further connected into a 3D network by the 2,6-dimethylpyrazine ligands. Powder X-ray diffraction (PXRD) proves that a pure crystalline phase has been obtained.
