Description
From the study of the hypothetical series Pb/sub 2//sup II/[Pb/sub 2+2p-2c//sup IV/In/sub c-2p/Sb/sub c/]O/sub 6+p/ (O <= p < 1; 0 <= c < 2), the existence of the cubic pyrochlore Pb/sub 2//sup II/[In/sub 0.5/Sb/sub 1.5/]O/sub 6.5/ has been established. This compound was obtained as an organe yellow powder, S.G. Fd-4m (No. 227), Z = 8, a = 10.5892(1) A, V = 1187.38(3) A3, D/sub c/ = 8.48 M gm-3. For Pb in 16(c) positions, In and Sb (1:3) randomly distributed in 16(d), oxygen atoms in 48(f) and in a half of the 8(a) sites, and oxygen positional parameter x = 0.429 (origin at center, -3m), R = 0.062. The apparent interatomic distances (A) are determined: Pb-O = 2.612; (In, Sb)-O = 2.019. (author)
