Crystal structure of a low-spin poly[di-μ₃-cyanido-di-μ₂-cyanido-bis-(μ₂-2-ethyl-pyrazine)-dicopper(I)iron(II)].

ABSTRACT: In the title metal-organic framework, [Fe(C₆H₈N₂)₂{Cu(CN)₂}₂] _n , the low-spin Fe^II ion lies at an inversion centre and displays an elongated octa-hedral [FeN₆] coordination environment. The axial positions are occupied by two symmetry-related bridging 2-ethyl-pyrazine ligands, while the equatorial positions are occupied by four N atoms of two pairs of symmetry-related cyanide groups. The Cu^I centre is coordinated by three cyanide carbon atoms and one N atom of a bridging 2-ethyl-pyrazine mol-ecule, which form a tetra-hedral coordination environment. Two neighbouring Cu atoms have a short Cu⋯Cu contact [2.4662 (7) Å] and their coordination tetra-hedra are connected through a
