Curiouser and curiouser: By combining high-resolution molecular spectroscopy in the centimeter and millimeter wave regions, and high-level coupled-cluster quantum-chemical calculations, the structure of the HPSi molecule has been determined. The bridged geometry of HPSi is in remarkable contrast to that of the C and/or N analogues, such as HCN/HNC, HCP, and HNSi, which are all linear.
