Abstract
A mixed valence copper(II)–copper(I) coordination polymer has been synthesized starting from a copper(II) salt at ambient condition and characterized by IR and Raman spectra and single crystal X-ray diffraction. The structure of the complex consists of a 1-D infinite chain with repeating unit [Cu(1,2-pn)2(μ3-I)Cu2(μ2-I)3(CH3CN)] and a free CH3CN, where 1,2-pn = 1,2-diamino-1-propene. The complex shows a very short copper(I)–copper(I) distance (2.412 Å).
