Disphenoidal species

In general, the R2BiX type compounds coordinate one two-electron donor (L) to afford a four-coordinate disphenoidal species R2BiX L, whilst the RBiX2 type compounds coordinate two two-electron-donors, giving a five-coordinate, square-based pyramidal species RBiX2-L2 (Figs. 2.2 and 2.3).
