Abstract :
X-ray powder data originally published for innelite Na2Ba3(Ba,K,Mn)(Ca,Na)Ti(TiO2)2[Si2O7]2(SO4)2-were erroneously those of catapleiite. The new data reported here are compared with powder data calculated from the published structure. The cell is triclinic (space group P1, Z=l), a-14.71(1) A, b=7.115(7) A, c=5.379(4)A, (alfa) =90.02(7)degree, (beta)=94.68(8)°, (gamma)=98.43(9)°, V=555.0(6) A^3, F3o=5.2(0.053,109).
