摘要：

The development of new compounds in the domain of metal dinitridocarbonates is most efficiently performed via solid-state metathesis or simply by addition reactions. Our discovery of Pb7I6(CN2)(4) is the result of a solid-state reaction of PbCN2 with PbI2 at 420 degrees C. Its crystal structure was solved and refined from X-ray diffraction data based on a single crystal with the space group P6(3)/mmc. The crystal structure is based on a network of lead tetrahedra, lead trigonal bipyramids and lead octahedra interconnected by [NCN](2-) and iodide. Properties of the material were investigated by diffuse reflection measurement, photoluminescence measurements, and electronic band structure calculations demonstrating that this material is a semiconductor.
