The coordination chemistry of dithiophosphonates: An emerging and versatile ligand class

Preparation and Characterization of Phenyl Phosphine Diselenide – The Monomeric Form of Woollins' Reagent

“…[9][10][11] Evidence for the existence of RPE 2 species is scarce and indirect as it comes from trapping experiments. [9][10][11] Evidence for the existence of RPE 2 species is scarce and indirect as it comes from trapping experiments.…”

Perplexing Coordination Behaviour of Potentially Bridging Bipyridyl-Type Ligands in the Coordination Chemistry of Zinc and Cadmium 1,1-Dithiolate Compounds

“…In the centrosymmetric molecule, the NS4 donor set approximates a trigonal-bipyramidal geometry (τ = 0.80) with the less tightly bound sulphur atoms The 1,2-bis(4-pyridylmethylene)hydrazine (4-pyald; 4-pyridylaldazine) ligand is the first example of a bipyridyl-type ligand in this survey with heteroatoms in the bridge linking the 4-pyridyl residues. With four atoms in the link-that is, an all-trans CN 2 C sequence, separating the 4-pyridyl residues-there is sufficient space to accommodate the bulky cyclohexyl groups in {Zn[S 2 P(OCy) 2 ] 2 (4-pyald)} n (22) [40], and a zig-zag coordination polymer ensues, Figure 6a. The curious feature of this structure relates to the relative disposition of the sulphur atoms.…”

Exploring the crystallization landscape of cadmium bis(N-hydroxyethyl, N-isopropyldithiocarbamate), Cd[S2CN(iPr)CH2CH2OH]2

“…Binuclear 2 is centrosymmetric with two ligands being µ2κ 2 -tridentate as for 1 but the other two being κ 2 -chelating leading to square pyramidal geometries. The conversion of the kinetic crystallization product, 1, to thermodynamic 2 is irreversible but transformations mediated by recrystallization ( (5). These arise as a result of decomposition/oxidation of the…”

“…as lubricants, in the vulcanization of rubber, as flotation agents, etc. [3][4][5] of metal 1,1-dithiolates comprising ligands such as dithiocarbamate ( -S2CNR2), xanthate ( -S2COR), and dithiophosphate [ -S2P(OR)2]. Therefore, it is not surprising that a vast amount of structural data for this class of compound exists as summarized in a number of bibliographic reviews [6][7][8][9][10].…”
