It seems i found the answer: those 2D pictures are huge simplifications. in reality Si and Ge have diamond structures. Plus you have to keep in mind orbital hybridization. Here is the best description of semiconductor structures and bonding:

Hi! I study semiconductors and I am confused with the bonding picture for semiconductor crystals. For example, it is said that in Si crystal one can find covalent bonds. In the most books this bonds are shown like that: 2D crystal structure where lines between atoms are a covalent bonds, each...
