Highly crystalline lead sulfide has been prepared by the thermolyses o
f compounds of the general formula Pb(SR)2. Three isomeric lead bis(bu
tylthiolate) compounds have been isolated and characterized by IR, H-1
NMR, and elemental analyses. Their solid-state decomposition, as well
as their thermolysis in suspension in a refluxing hydrocarbon, has be
en studied. Decomposition has been carried out at temperatures as low
as 190-degrees-C. XRPD patterns and SEM micrographs of the obtained Pb
S are discussed. Elemental analysis and ESCA data indicate the presenc
e of highly pure PbS. All gaseous byproducts have been isolated and id
entified, and the origins of their chemical production have been locat
ed.
