Poly[[[μ-trans-1,2-bis­(pyridin-4-yl)ethene-κ2N:N′]-μ-iodido-copper(I)]–trans-1,2-bis­(pyridin-4-yl)ethene (1/0.25)]

ABSTRACT: In the title polymer, oligomeric stairsteps are composed of rhombus dimers of Cu2I2 that are bridged by 1,2-bis­(pyridin-4-yl)ethene ligands. The title compound, {[CuI(bpe)]·0.25(bpe)}n, was synthesized similarly to (CuI)2(bpe) [Neal et al. (2019 ▸). IUCrData, 4, x190122] with red crystals grown from aceto­nitrile solutions of CuI and the bpe ligand [bpe = 1,2-bis­(pyridin-4-yl)ethene, C12H10N2]. The structure of the title compound is a type 1 complex in the Graham nomenclature [Graham et al. (2000 ▸). Inorg. Chem. 39, 5121–5132], having rhombic dimers of Cu2I2 that are bridged by two bpe ligands, to form oligomeric ribbons arranged as stairsteps. The step height is 2.8072 (11) Å, which is the Cu—Ii distance of the dimer [symmetry code (i): 1 − x, 2 − y, 1 − z]. The resulting polymer displ
