The paper reviews the polyanionic hexagons of silicon and germanium, focusing on aromaticity. The chair-like structures of hexasila-and hexagermabenzene are similar to a nonaromatic cyclohexane (CH 2 ) 6 and dissimilar to aromatic D 6h -symmetric benzene (CH) 6 , although silicon and germanium are in the same group of the periodic table as carbon. Recently, six-membered silicon and germanium rings with extra electrons instead of conventional substituents, such as alkyl, aryl, etc., weredoi:10.3390/sym2041745 fatcat:mtarmmxtyzdrfpjxteldguhi4q
