Poly[di-μ₃-chloro-μ₂-1,2-di-4-pyridylethene-1:2κ² N,N′-dicopper(I)]

Abstract

The structure of the title compound, [Cu2Cl2(C12H10N2)] n , shows that each CuI ion is tetrahedral, being coordinated by three Cl atoms and one N atom of the 1,2-bis(4-pyridyl)ethene ligand (BPE, C12H10N2). Cl atoms and BPE molecules bridge the CuI ions to form a two-dimensional layer structure through inversion centres located at the mid-point of the Cu2Cl2 bridge and at the mid-point of the C=C double bond of the BPE ligand.

Synthesis, crystal structure and thermal properties of poly[[μ-1,2-bis(pyridin-4-yl)ethene-κ2 N:N′-μ-bromido-copper(I)] 1,2-bis(pyridin-4-yl)ethene 0.25-solvate]

“…A further bridging coligand is 1,2-bis(pyridin-4-yl)ethene, for which some compounds have already been reported in the literature (see Database survey). These includes three liganddeficient compounds with the composition (CuX) 2 (4-bpe) (X = Cl, Br, I) in which the copper(I) cations are linked by the halide anions into chains, which are further connected into layers by the 4-bpe ligand (Li et al, 2006;Yang & Li, 2006;Chen et al, 2008;Wang, 2016;Shen & Lush, 2010;Blake et al, 1999;Neal et al, 2019). With CuI, a ligand-rich compound with the composition CuI(4-bpe)•0.25 4-bpe has already been reported, which is not known for CuBr and CuI (Hoffman et al, 2020).…”
