Single crystals of a new ternary nitride, Ba₅Si₂N₆, were synthesized by slow cooling from 750°C using a starting mixture of Ba, Si, Na and NaN₃, where Na and NaN₃ were a flux and a nitrogen source respectively. It crystallizes with orthorhombic symmetry: space group P2₁2₁2₁ (No. 19), a = 6.159, b = 10.305, c = 15.292 Å, and Z = 4. The crystal structure was determined from single-crystal data and refined to R1 = 0.0495 for all 1637 observed reflections and 89 variables. A pair of SiN₄ tetrahedra contained in the structure forms a nitridometallate anion of [Si₂N₆]^10- by edge sharing.
