Synthesis, Characterization and Crystal Structure of Bis(benzoyl-thiobenzoyl-methanato-O,S)diphenyl Lead

“…However, in diphenyllead bis(0,0'dibenzyldithiophosphate) (11) both dithiophosphate groups chelate the lead albeit in a n unsymmetrical fashion. 45 The selenium-organolead selenocarboxylates (13) and (14) The phenyllead dithioarsinates, Ph 4 _ rt Pb(S 2 AsR 2 ) n (n = 1 o r 2; R = Me o r Ph), a r e obtained similarly.…”

Heptacoordinated diphenyllead; hexa- and pentacoordinated triphenyllead and tin compounds derived from 5H-benzimidazo[1,2-c]quinazoline-6-thione

“…A coordinated THF occupies the cavity formed between the two phenyl and two phenylene groups, although this does not appear to be the reason for the open N-Pb-N angle. There are examples of other diphenyltin and diphenyllead compounds having two S N four-membered chelates rings, which have the same distortion with closed S- Pb-S and C-Pb-C angles and an open N-Pb-N angle [29][30][31][32]. An example is shown in Fig.…”
