Spatial distribution of 6s2 lone electron pair in Pb4Na(PO4)3 and stereochemical activity of the 6s2 electron cloud in lead‐bearing apatites

open access: yesActa Crystallographica Section B, EarlyView.
In lacunary apatite structure‐type Pb4Na(PO4)3, residual density attributable to the deformed 6s2 electron cloud is found in the vicinity of A2‐site Pb2+ on regular A2 triangle normal to c. Systematic comparison on the size of the A2 triangle with other apatite‐type compounds indicates limited stereochemical activity of the orbital.Single crystals of ...
