摘要
The new quaternary compound Ag2In2GeSe6 has been identified by means of X-ray, differential thermal and microstructural analyses. Its crystal structure has been determined using single crystal X-ray diffraction, spare group Cc, a=1.2692(3); b=0.7492(1); c=1.2644(3) nm; beta=109.50(3)degrees. Ag2In2GeSe6 is the first representative of a new structure type. The mode of tetrahedral cavity filling by cations in the Ag2In2GeSe6 and its relation with the AgGaGe3Se8 structure (AgGaGeS4 type) has been discussed. (C) 1999 Elsevier Science S.A.
