The Si-O-Si bond linking two tetrahedra is not straight (180°), but forms an angle of 144° in quartz (Fig.5). As a result, the overall crystal structure of quartz is quite complex. In other silica modifications this angle is different, while the angles inside the SiO 4 tetrahedra (defined by the O-Si-O bond) remain basically the same. The following table lists angles and distances for a few ...
