Single crystals of the quaternary compound Ba8Cu3In4N5 were prepared by heating Ba, Cu, and In in a Na flux at 1023 K under 7 MPa of N2, and by slow cooling from this temperature. The crystal structure was analyzed by single-crystal X-ray diffraction. It crystallizes in an orthorhombic cell (space group Immm (No. 71), Z=2) with a=4.0781(6), b=12.588(2), and c=19.804(3) Å at 298 K. The structural formula is expressed as Ba8[CuN2]2 [CuN]In4. Nitridocuprates of one-dimensional chains 1∞[CuN2/2] and isolated units 0[CuN2], and one-dimensional indium clusters 1∞[In2In4/2] are contained in the structure. A split-site model applied for the arrangement of 1∞[CuN2/2] chains suggested that there is a short-bond, long-bond alternation of the Cu-N bondings. The electrical resistivity of Ba8Cu3In4N5 was 3.44 mΩ·cm at 298 K. A metallic temperature dependence of the resistivity was observed down to 10 K. 相似文献
