摘要

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 ℃ 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].
