Crystalline cadmium dialkyl phosphorodithioate complexes: Synthesis and structural organization as probed by multinuclear 13C, 31P, and 113Cd CP/MAS NMR and single-crystal X-ray diffraction

Complexation of Cd(SeCN)2with imidazolidine-2-thione and its derivatives: Solid state, solution NMR and anti-bacterial studies

“…Although 113 Cd NMR studies have been performed on many thiolate ligand complexes, and this nucleus has a rich history in the literature as a metallobioprobe [6,7] there are, in fact, very few reports of 113 Cd NMR measurements on complexes containing SeCN − containing ligands [8]. The cadmium complexes present a significant advantage over their zinc counter parts from the structural characterization point of view, since 113 Cd NMR spectroscopy stands a sensitive probe of the coordination sphere of the cadmium ion.…”

Exploring the Topological Landscape Exhibited by Binary Zinc-triad 1,1-dithiolates

“…Nevertheless, new and unprecedented structural motifs occur, with the common feature of all motifs being an S 4 donor set for the central element; all structures crystallised solvent-free. Data for the 15 zinc-triad binary dithiophosphate structures, 21-35 [51][52][53][54][55][56][57][58][59][60][61][62][63], discussed in this section are presented in Table 2. (24) [54], and also features equal numbers of bridging and chelating ligands, but in this case leading to a dimeric aggregate, as illustrated for 24 in Figure 5b.…”

“…The eight-membered ring in motif J has the form of a boat with two sulphur atoms above and two below the plane through the Cd2P2 atoms. The remaining three structures, Cd[S2P(OR)2]2}2 for R = i-Pr (27) [52]; s-Bu (30) [58], Figure 6b; and Cy (31) [59], adopt motif I. A distinguishing feature of 31 is that the dimeric aggregate is disposed about a centre of inversion as opposed to 2-fold symmetry for 27 and 30.…”

A pyridine adduct of bis(di-iso-butyldithiocarbamato-S,S′)cadmium(II): Multinuclear (13C, 15N, 113Cd) CP/MAS NMR spectroscopy, crystal and molecular structure, and thermal behaviour

“…In our previous works [6,7], we have systematically studied binuclear dialkyldithiocarbamate cadmium(II) complexes, [Cd 2 (S 2 CNR 2 ) 4 ] (R = C 2 H 5 , C 3 H 7 , iso-C 3 H 7 , C 4 H 9 , iso-C 4 H 9 ; R 2 = (CH 2 ) 5 , (CH 2 ) 6 ) by means of multinuclear 13 C, 15 N, 113 Cd CP/MAS NMR spectroscopy, including analysis of 113 Cd chemical shift anisotropy, and reported the syntheses and molecular structures of two cadmium(II) dithiocarbamates, R = C 3 H 7 [6], R 2 = (CH 2 ) 5 [7]. In the molecular structures of the latter two cadmium(II) complexes, experimental 15 N NMR resonances have been assigned to the dialkyldithiocarbamate ligands with various structural functions.…”

“…In the molecular structures of the latter two cadmium(II) complexes, experimental 15 N NMR resonances have been assigned to the dialkyldithiocarbamate ligands with various structural functions. The differences in the isotropic 15 N chemical shifts of the terminal chelating and tridentate bridging dithiocarbamate ligands have been interpreted, invoking the concept of joint manifestation of the mesomeric effect of @N-C(S)S À groups and the (+)inductive effect of the alkyl substituents [6,7]. Recently, we also reported the high chemisorption activity of binuclear cadmium(II) N,N-dialkyldithiocarbamates (R = iso-C 4 H 9 and C 4 H 9 ) with respect to [AuCl 4 ] À ions in 2 M hydrochloric acid solutions and the formation of heteropolynuclear gold(III)-cadmium(II) complexes, ([Au{S 2 CN(iso-C 4 H 9 ) 2 } 2 ] 2 [CdCl 4 ]) n [8,9] and ([NH 2 (C 4 [10] as the fixation modes of gold(III).…”
