The new compound La 3 (OBN 2 )O 2 was prepared by a solid state reaction of LaOCl and Li 3 (BN 2 ) at 1200 °C in a fused niobium ampoule. A single crystal structure refinement [ Pnma , Z = 4, a = 1269.8(2) pm, b = 368.94(5) pm, c = 1101.1(2) pm] indicates the presence of a planar (OBN 2 ) 5– ion, which is structurally related to the (BN 3 ) 6– ion. The arrangement of atoms in the structure corresponds to a slightly modified structure of Ca 3 (CBN)Cl 2 [ Pnma , Z = 4, a = 1386.7(9) pm, b = 384.7(3) pm, c = 1124.7(6) pm].
