Two 1D [CuxIx]-based coordination polymers of tetraphosphine ligands

Two 1D [CuxIx]-based coordination polymers [Cu2I2(dppeda)]·2MeCN (dppeda = N,N,N′,N′-tetra(diphenylphosphanylmethyl)ethylene diamine)) and [Cu4I4(dpppda)]·MeCN (dpppda = 1,4-N,N,N′,N′-tetra(diphenylphosphanylmethyl)benzene diamine) were isolated from solvothermal reactions of CuI with dppeda or dpppda. Both complexes were structurally characterized by elemental analysis, IR, 1H and 31P{1H}, and X-ray crystallography and their stability in solution and in solid state were studied by ESI-MS and thermogravimetric analysis.
