Synthesis and crystal structure of a new isomer of poly[di-μ₃-cyanido-μ-2,6-di-methyl-pyrazine-dicopper(I)].

ABSTRACT: The title compound, [Cu₂(CN)₂(C₆H₈N₂)] _n or Cu₂(CN)₂(2,6-di-methyl-pyrazine), was prepared by the reaction of copper(I) cyanide with 2,6-di-methyl-pyrazine in water. Its asymmetric unit consists of two crystallographically independent copper(I) cations and cyanide anions as well as one crystallographically independent 2,6-di-methyl-pyrazine ligand in general positions. Each copper cation is fourfold coordinated by one N atom of the 2,6-di-methyl-pyrazine 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
