The acw compound was studied by X-ray diffraction, electron probe, X-ray microanalysis, chemical analysis and SEM. The result of X-ray powder diffraction shows that NaBa2 Li0.6 Nb4.8 Zn0.2 O15 belongs to orthorhombic tungsten bronze structure, with space group Pba2( 32 ) and lattice parameters a = 12.6115(2)A, b = 12.4981(2)A, C = 3.9479(3)A.
