Abstract

Through a diffusion reaction, cuprous bromide, triphenyl­phosphane and 1,3-bis­(pyridin-4-yl)propane (bpp) were self-assembled to form the one-dimensional title compound, [Cu2Br2(C13H14N2)(C18H15P)2]n. Each CuI atom is coordinated by two Br atoms, one P atom from a triphenyl­phosphane ligand and one N atom from a bpp mol­ecule in a distorted tetra­hedral geometry. Two μ2-Br bridges connect two [Cu(PPh3)]+ units to form neutral [CuBr(PPh3)]2 dimers, which are linked by the flexible bridging bpp ligands to form a one-dimensional chain structure parallel to the c axis. The dihedral angle between the pyridine rings of the bpp ligand is 34.59 (14)°.
