“…The observed decrease in δ( 31 P)-values (≈10-15 ppm) is a result of the covalent linkage between the Dtp groups and the metal atom in the lead(II) Dtp complexes, which is in agreement with our previous 31 P CP/MAS NMR studies on dialkyldithiophosphate nickel(II) [22], zinc(II) [1,22], cadmium(II) [23][24][25][26], silver(I) [27] and tetraphenylantimony(V) [28,29] complexes.…”

“…The main bond lengths defined are shown in Table 2. The T1-S distances [2.819(4)-3.268 (4) Å] fall near the values found in other related compounds [16,17]. T1-O bond lengths of 3.110(4) and 3.217 (4) Å are longer than those for Tl(DL-HCys) [15] (2.86 and 3.06 Å), however similar and even larger distances T1-O are established in other structures [16] for example 3.21 and 3.40 Å in [24].…”

†Electronic supplementary information (ESI) available. See DOI:xxx The isolation of thallium(I) complexes [Tl 2 (HCys) 2 ] n (1) and [Tl 4 (HCys) 4 ] n (2) {H 2 Cys = L-Cysteine} from aqueous solution by means of crystallization is reported herein. Polar crystals of 1 and 2 were crystallized in P2 1 and P2 1 2 1 2 1 space groups respectively. Elemental analysis, XRD, IR, UV-Vis, TG-DSC and a single crystal X-ray diffraction were applied for characterizing the compounds. Linkage isomers 1 and 2 have 1D and 2D coordination polymeric structures respectively. The lone pair electrons of thallium(I) in 1-2 are stereo-chemically active. In 1, each of two independent Tl + ions is coordinated by three HCysions forming TlS 3 O irregular polyhedron that is linked to each other by vertexes in an infinite chain. In 2, four independent Tl + ions are coordinated by HCysions through S and O atoms, forming Tl1S 3 O 2 , Tl2S 4 , Tl3S 3 , Tl4S 3 irregular polyhedrons. The crystallographic independent HCysions are linked to the metal ion differently, two are μ 3 -S,S,S-, one is μ 4 -O,S,S,S-, and one is μ 4 -O,O',S,S,S-coordinated ligands. The amine group of compounds 1 and 2 is in the form of an ammonium ion (−NH 3 + ). The structures of 1-2 are stabilized by N-H⋯O hydrogen bonds, thallophilic Tl•••Tl and anagostic Tl⋯H-C interactions. The spectroscopic and thermal properties of compounds were analyzed.

“…Analysis of the obtained results indicates that the anisotropy parameters and the principal values of 31 P chemical shift tensors for all four states of the Dtph groups are qualitatively similar: in all cases, δ aniso is negative, while the η values reflect approximately equal contributions of the axially symmetric and rhombic components to the chemical shift tensors. Studies of mono , bi , tetra , hexa , and polynuclear diisopropyl dithiophosphate complexes of nickel(II) [10], cadmium [8], zinc [28,29], lead (II) [30,31], sil ver(I) [32], platinum(II) [33], and thallium(I) [34], which we carried out previously, demonstrated that irrespective of the chemical nature of the complexing agent, the δ aniso value for bridging Dtph ligands is always negative, i.e., the direction of the MAS NMR spectra is determined by the condition δ zz < δ yy , δ xx ; the modulus of δ aniso is usually well correlated with the S-P-S angle [28]. Thus, it is clear that all Dtph groups in the obtained gold complex occupy bridging positions.…”

Previously [1][2][3][4][5], we studied the chemisorption properties of binuclear cadmium dialkyldithiocar bamate complexes, [Cd 2 {S 2 CNR 2 } 4 ] (R = C 4 H 9 , iso C 4 H 9 , iso C 3 H 7 and R 2 = (CH 2 ) 5 ) with respect to solutions of AuCl 3 in 2M HCl. A number of gold(III)-cadmium heteropolynuclear complexes, in particular, ([Au(S 2 CNR 2 ) 2 ] 2 [CdCl 4 ]) n (R = iso C 4 H 9 [1, 2], iso C 3 H 7 [3]), ([NH 2 (C 4 H 9 ) 2 ][Au{S 2 CN(C 4 H 9 ) 2 } 2 ][CdCl 4 ]) n [4] and polynuclear complexes ([Au(S 2 CNR 2 ) 2 ][AuCl 4 ]) n (R = C 4 H 9 , R 2 = (CH 2 ) 5 ) [5], were isolated from the sorption systems on a preparative scale as individual gold(III) containing species. The intricate supramo lecular structure and the thermal behavior of the iso lated compounds were studied. The results attest to good prospects of using complexes with dithio ligands as chemisorbents for binding noble metals from dilute process solutions and for waste water treatment to remove heavy metal cations. Therefore, it was of inter est to study the chemisorption properties of complexes with another type of dithio ligands: dialkyl dithiophos phate ions (RO) 2 P(S)S -.This work is concerned with the chemisorption interaction of freshly precipitated nickel(II) and cad mium diisopropyl dithiophosphate complexes,and [Cd 2 {S 2 P(O iso C 3 H 7 ) 2 } 4 ], with [AuCl 4 ] -in 2M HCl. It was found that binding of gold(III) from the solution is accompanied by its reduction to gold(I) as a result of oxidation of some Dtph groups to the corresponding disulfide. The polynuclear gold(I) complex [Au 2 {S 2 P(O iso C 3 H 7 ) 2 } 2 ] n (I) was isolated from the chemisorption Abstract-The paper deals with reactions of freshly precipitated diisopropyl dithiophosphate (Dtph) com plexes of nickel(II), [Ni{S 2 P(O iso C 3 H 7 ) 2 } 2 ] and cadmium, [Cd 2 {S 2 P(O iso C 3 H 7 ) 2 } 4 ], with the [AuCl 4 ] -in 2M HCl, resulting in gold transition from the solution to the precipitate as polymeric gold(I) diisopropyl dithiophosphate. The reduction of gold(III) to gold(I) noted in both cases is due to oxidation of the relevant part of the Dtph group to bis(O,O' di (iso) propoxythiophosphoryl) disulfide, (iso C 3 H 7 O) 2 P(S)S-S(S)P(O iso C 3 H 7 ) 2 . The polynuclear gold(I) complex [Au 2 {S 2 P(O iso C 3 H 7 ) 2 } 2 ] n (I) was isolated on a pre parative scale from the chemisorption system and studied by MAS 31 P NMR and X ray diffraction. The key structural unit of I is the non centrosymmetric binuclear molecule [Au 2 {S 2 P(O iso C 3 H 7 ) 2 } 2 ] in which the gold atoms are connected by two bridging Dtph groups. The structure contains two types of non equivalent binuclear molecules related as conformational isomers. Owing to the relatively weak Au-Au contacts, the neighboring binuclear [Au 2 {S 2 P(O iso C 3 H 7 ) 2 } 2 ] molecules are involved in an infinite polymeric chain with conformer alternation along the chain. To elucidate the conditions for the recovery of bound gold(I), the pre cipitates formed in the sorption systems were studied by simultaneous ther...
