Neue Metallderivate des Thiophens, I.: Tetra‐α‐thienylzinn und Tetra‐α‐thienylblei

Organolead Compounds.

“…The work of Kharasch (185,187,188,189,190) on organomercury compounds is particularly well known. Other investigations have involved organotin (19,29) or organolead (9, 11, 12, 132, 135, 182) compounds, and sometimes different cleaving reagents (8,141,175,182,218,219,221,222,223,224). Some of the results obtained with lead compounds are discussed here.…”

The crystal structures of the tetra(2-thienyl) derivatives of germanium, tin and lead

“…These were prepared following published procedures and in each instance recrystallized from absolute ethanol in the form of long glistening needles (Krause & Renwanz, 1927, 1932. For each substance, indexed Weissenberg photographs revealed tetragonal symmetry and systematic absences, h odd for h00, l odd for hhl, uniquely determined the space group to be P42~c.…”
