The phenomenon of bond stretch isomerism , two isomers of a compound differing predominantly in just one bond length, is one of those chemical concepts that wax and occasionally wane.[cite]10.1016/S1631-0748(02)01380-2[/cite] Here I explore such isomerism for the elements Ge, Sn and Pb. In one earlier post, I noted a form of bond stretch isomerism that can arise from a Jahn-Teller distortion ending in two different geometries

Hemi- and holo-directed lead(ii) complexes in a soft ligand environment

Structures and stereochemical activity of the lone pairs at the lead ion were investigated by synthetic, spectroscopic and structural studies of ten lead(ii) complexes with heterocyclic soft ligands. The majority of the complexes exhibited a hemi-directed environment around the lead ions.
