Abstract

Single crystals of new quaternary compounds Sr8Cu 3In4N5 and Sr0.53Ba 0.47CuN were prepared, respectively, from a Sr-Cu-In-Na melt under 7MPa of N2 and from a Sr-Ba-Cu-In-Na melt under 0.5MPa of N 2 by slow cooling from 1023 to 823K. The crystal structures were determined by single-crystal X-ray diffraction. Sr8Cu 3In4N5 has an orthorhombic structure (space group, Immm, Z=2, a=3.8161(5)Å, b=12.437(2)Å, c=18.902(2)Å), and is isostructural with Ba8Cu3In4N 5. It contains nitridocuprates of isolated units 0[CuN2] and one-dimensional linear chains 1[CuN2/2] and one-dimensional indium clusters 1[In2In2/2]. Sr 0.53Ba0.47CuN crystallizes in an orthorhombic cell, space group Pbcm, Z=4, a=5.4763(7)Å, b=9.2274(12)Å, c=9.0772(12)Å. The structure contains infinite zig-zag chains 1[CuN2/2] which kink at every second nitrogen atom.
