Differing Coordination Modes of (O‐Alkyl)‐p‐Ethoxyphenyldithiophosphonato Ligands in Copper(I), Silver(I) and Gold(I) Triphenylphosphine Complexes

Abstract

The three (O‐methyl)‐p‐ethoxyphenyldithiophosphonato triphenylphosphine complexes of copper, silver and gold, [(Ph3P)nM{S2P(OMe)C6H4OEt‐p}] (M = Cu, n = 2; M = Ag, Au, n = 1) investigated structurally by X‐ray diffraction exhibit remarkable structural differences. The copper compound is a four‐coordinate chelate monomer with Cu–S 2.4417(6) and 2.5048(6) Å; P–Cu–S 104.24(2)–114.01(2)°; Cu–S–P 82.49(3)° and 80.85(2)°. The silver compound is a cyclic dimer with bridging dithiophosphonato ligands and three‐coordinate silver atoms [Ag–S 2.5371(5) and 2.6867(5) Å; P–Ag–S 122.88(2)° and 122.17(2)°; Ag–S–P 89.32(2)° and 103.56(2)°]. The gold compound is monomeric with linear dicoordinate gold [Au–S 2.3218(6) Å; P–Au–S 177.72(2)°, Au–S–P 100.97(3)°].

“…Data collection: APEX2 (Bruker, 2007); cell refinement: SAINT (Bruker, 2007); data reduction: SAINT; program(s) used to solve structure: SHELXS97 (Sheldrick, 2008); program(s) used to refine structure: SHELXL97 (Sheldrick, 2008); molecular graphics: ORTEP-3 for Windows (Farrugia, 1997); software used to prepare material for publication: WinGX (Farrugia, 1999) and PLATON (Spek, 2009). Dithiophosphorus compounds and their complexes have been widely investigated in last decades (Heiduc et al, 2006;Karakuş et al, 2007;Gataulina et al, 2008). They have been utilized in agricultural, industrial and medicinal products such as additive to lubricant oils, solvent extraction reagents for metals, floatation agents for minerals, pectidites and insecticides (Thomas et al, 2001;Gray et al, 2003).…”

Polymeric Organometallic Architectures of Novel PSe Anions

“…Current synthetic efforts in the field concentrate on metal complexes with ligands designed by formally replacing O atoms in phosphate ions with OR, SR, S, Se, OSe and combinations thereof, and ultimately on the construction of larger molecular aggregates. [15][16][17][18][19][20] In previous work, it was shown that reactions of metal salts MX (X = alkoxide, thiolate, carboxylate) with Lawessons reagent (L.R.) [{RP(S)A C H T U N G T R E N N U N G (m-S)} 2 ] (R = 4-anisyl) [21] or the analogous Se compound Woollins reagent (W.R.) [{PhP(Se)A C H T U N G T R E N N U N G (m-Se)} 2 ] [8,22] offer an alternative route to complexes containing P/S-or P/Se-based anionic ligands.…”

Synthesis, characterization, electrospinning and antibacterial studies on triphenylphosphine-dithiphosphonates Copper(I) and Silver(I) complexes

“…The IR spectrum of the ligands and their complexes showed two characteristic bands at around 692–642 cm −1 and 582 – 515 cm −1 which are assigned to ν as (PS 2 ) and ν s (PS 2 ), respectively [ 36 , 37 ].…”
