Poly[[μ2-1,2-bis(4-pyridyl)ethene-κ2N:N′]-di-μ3-bromido-dicopper(I)

Abstract

In the title polymeric CuI compound, [Cu2Br2(C12H10N2)]n, the Cu cation is coordinated by an N atom from the 1,2-bis­(4-pyrid­yl)ethene ligand and three Br− anions in a distorted tetra­hedral CuBr3N coordination geometry. Each Br− anion bridges three Cu cations related by inversion centers, forming a stair-like polymeric chain along the a axis, and the terminal N atoms of the 1,2-bis­(4-pyrid­yl)ethene ligand, located across an inversion center, coordinate the Cu cations from neighboring chains, forming polymeric sheets.
