Crystal Structure of Diphenylbis(diphenyldithiophosphinato)lead(IV), PbPh2(S2PPh2)2.

Lead(IV) complexes with phosphinoyldithioformates, R2P(O)CS2− (R = Ph or PhCH2). Syntheses and characterization. Crystal structures of [PPh4][S2CP(O)Ph2]·0.5H2O, [PbPh2{S2CP(O)Ph2}2] and [PbPh2Cl{S2CP(O)Ph2}]

“…The Pb-S distance is comparable to the short Pb-S distance in six-co-ordinated trans-[PbPh 2 (S 2 PPh 2 ) 2 ] [2.6556( 7) Å] which, however, also has a significantly longer Pb-S distance [3.0171( 6) Å]. 6 In this complex the bonding of Ph 2 PS 2 Ϫ was therefore characterized as anisobidentate. In the present complex the Pb-O bonds are also rather long compared to the Pb-S bonds, and accordingly the P-O distances are only slightly longer than in the "free" ligand.…”

Using coordination chemistry to develop new routes to semiconductor and other materials

“…In the case of dichalcogenophosphinate complexes, sulfur derivatives have been investigated extensively [27][28][29][30][31][32][33] while studies on the seleno analogue are limited due to the difficulty of the synthesis process. The first synthesis of diselenonophosphinate ligand and complexes were reported by Kuchen et al [34][35][36].…”
