Abstract

Single crystals of the ternary nitrides Sr6Cu3N5 and SrCuN were prepared in high pressure autoclaves at 800 °C. Tetragonal crystals of the nitridocuprate, Sr6Cu3N5 crystallized in space group P42mc (no. 105), a=8.649(1) Å, c=7.325(1) Å. This compound represents a new structure type characterized by a mixture of linear (CuIN2)5- and unprecedented V-shaped (CuI2N3)7- nitridometallate anions. The crystal structure of SrCuN was confirmed by single crystal data to adopt the BaNiN structure type (Pnma (no. 62), a=9.045(2), b=13.234(3), c=5.388(1) Å; Z=12).
