Crystal structure of poly[bis-(μ-2-bromo-pyrazine)-tetra-μ₂-cyanido-dicopper(I)iron(II)]: a bimetallic metal-organic framework.

ABSTRACT: In the title metal-organic framework, [Fe(C₄H₃BrN₂)₂{Cu(CN)₂}₂] _n , the Fe^II cation is located on an inversion center and has a slightly elongated octa-hedral coordination environment [FeN₆], ligated by two pyrazine N atoms of symmetry-related bridging 2-bromo-pyrazine mol-ecules in the axial positions and by four N atoms of pairs of symmetry-related cyanido groups in the equatorial positions. The Cu^I center has a fourfold coordination environment [CuC₃N], with an almost perfect trigonal-pyramidal geometry, formed by three cyanido C atoms and an N atom of a bridging 2-bromo-pyrazine mol-ecule. Copper(I) centers related by a twofold rotation axis are bridged by two
