P. Espinet et al., PALLADIUM COMPLEXES WITH THE TRIDENTATE DIANIONIC LIGAND PYRIDINE-2,6-BIS(THIOCARBOXYLATE), PDTC - CRYSTAL-STRUCTURE OF (N-BU4N)[PD(PDTC)BR], Inorganic chemistry, 33(9), 1994, pp. 2052-2055
The reaction of [Pd(acac)2] with pyridine-2,6-bis-(thiocarboxylic) aci
d (H-2pdtc) in chloroform affords [Pd(pdtc)]2, which has been used as
starting material in the preparation of a variety of neutral and anion
ic complexes [Pd(pdtc)L]0,- containing the planar tridentate ligand pd
tc. The X-ray structure of (n-Bu4N)[Pd(pdtc)Br] shows the pdtc dianion
as a S,N,S-tridentate chelate ligand forming two strain-free palladac
ycles.
