Ge 10 cluster, Na 4 (Ge,Si) 9 O 20 , hydrothermal. A Si modified Ge 10 cluster with structure Na 4 (Ge,Si) 9 O 20 (denoted as HUT-1) was synthesized by hydrothermal synthesis at 160 Β°C with a sodium silicate source. The compound was characterized by single crystal, powder X-ray diffraction and TGA-
