Three-pointed planar Si4 stars with unelucidated bonding and planar Si5 rings have been found in Li12Si7. In the formulation shown below with x = 4 and y = 10 the star could be an excited tetrahedrane state as Simath image; for x = y = 8 the star would be Simath image and isoelectronic with the carbonate ion.
