“…The crystal structure of a colourless derivative [203] is built up from hexameric molecules of (Table 14(A)) in which two identical bridging atoms are found, for example: O-donors [190,[207][208][209][210][211][212][213][214][215][216]; CI atoms [217]; S-donors [171,[218][219][220][221][222][223][224][225][226][227][228]; Br atoms [217,229] and I atoms [217,[230][231][232][233]. The geometry about the Pb [190,207], trigonal bipyramidal [208,222,223,225,227,233], pseudo-octahedral [209][210][211][217][218][219]…”

This review covers over three hundred and sixty coordination and organometallic complexes of lead. About 20% of these contain lead in its +4 oxidation state, of which one fifth are dilead(+6) units, and two are anionic clusters. The Pb(IV) derivatives are predominantly organometallic, many stabilized by sandwich ligation. The majority of the Pb(ll) compounds are typical coordination complexes. Mon-to polynuclear derivatives are found, with coordinations numbers from 2 to 12. The effect of the non bonded pair of valence electrons is observed in lower coordination number Pb(ll) complexes. Examples of distortion, geometric and coordination isomerism are observed. Factors affecting bond lengths and bond angles are discussed, and some ambiguities in coordination polyhedra are outlined.
