Abstract: In the title compound, [Cu(CN)(C₄H₅N₃)]_n or [Cu( [mu] -CN)( [mu] -PyzNH₂)]_n (PyzNH₂ is 2-aminopyrazine), the Cu^I center is tetrahedrally coordinated by two cyanide and two PyzNH₂ ligands. The Cu^I-cyano links give rise to [Cu-CN] chains running along the c axis, which are bridged by bidentate PyzNH₂ ligands. The three-dimensional framework can be described as being formed by two interpenetrated three-dimensional honeycomb-like networks, both made of 26-membered rings of composition [Cu₆( [mu] -CN)₂( [mu] -PyzNH₂)₄].

Formula: [Cu(CN)(C₄H₅N₃)]
