The interplay of $sp^2$- and $sp^3$-type bonding defines silicon allotropesin two- and three-dimensional forms. A novel two-dimensional phase bearingstructural resembleance to a single MoS$_2$ layer is found to possess a lowertotal energy than low-buckled silicene and to be stable in terms of its phonondispersion relations. A new set of cigar-shaped, nematic orbitals originatingfrom the Si $sp^2$ orbitals realizes bonding with a 6-fold coordination of theinner Si atoms of the layer. The identification of these nematic orbitalsadvocates diverse Si bonding configurations different from those of C atoms.
