title: beta-Rubidium antimonide, Rb4Sb4.
abstract: beta-RbSb crystallizes with the LiAs structure type. As in the alpha phase (NaP type), Sb(-) forms approximate 4(1) helical chains (2(1) crystallographic symmetry), with Sb-Sb distances of 2.838 (1) and 2.862 (1) A. In contrast to the alpha phase, the helices have different chirality.
