| 英文摘要 | A new heterometallic iodide, pbi4cu2(pph3)(4), was synthesized by reactions of pbi2, cui and triphenylphosphine (pph3) in dmf solution. the single-crystal x-ray diffraction analyses show that pb(ii) center adopts an unusual cis-divacant octahedral geometry. crystal data: triclinic, space group p (1) over bar, a = 12.3455(2)angstrom, b = 13.8673(1)angstrom, c = 21.3421(1)angstrom, alpha = 106.623(4)degrees, beta = 103.478(6)degrees, gamma = 93.574(5)degrees, v = 3371.83(6)angstrom(3) and z = 2. density function theory (dft) calculations and fragment orbital interaction analyses reveal the presence of a three-center four-electron (3c-4e) hypervalent bonding about lead; and the formation of the unusual cis-divacant [pbi4](2-) octahedron is energetically favorable. the title yellow compound has an optical bandgap of 2.69 ev and shows remarkable red-infrared fluorescence emission at 732 nm with lifetime of 24 mu s which is assigned as an iodine 5p-lead 6s to pph3-lead 6p charge transfer (xm-lm-ct).
