The structures of two germanium-rich thorium germanides were found to have C-face-centered orthorhombic symmetry. One of the phases represents a new structure type; the second has the C49(ZrSi/sub 2/)-type structure, is isostructural with UGe/sub 2/, and ls probably stoichlometric ThGe/sub 2/. The first structure can be derived from the second by a slmple ctystallographlc translation of some of the component atoms. The structures are discussed in the light of their close relationship with the anti-C38(Fe/sub 2/AS)-type phases ThAs/ sub 2/, ThSb/sub 2/, and ThBi/sub 2/ and their similarity to the polymorphs of ThSi/sub 2/. The first phase is thought to have a defect structure and a composition close to Th/sub 0.9Ge/sub 2/. (auth)
