Fixation modes of gold(III) from solutions using cadmium(II) dithiocarbamates. Preparation, supramolecular structure and thermal behaviour of polynuclear and heteropolynuclear gold(III) complexes: Bis(N,N-dialkyldithiocarbamato-S,S′)gold(III) polychlorometallates, [Au(S2CNR2)2]nX (n=1: X=[AuCl4]−; n=2: X=[CdCl4]2−, [Cd2Cl6]2−)

Synthesis, Crystal Structure, and Selected Properties of [Au(S2CNH2)2]SCN: A Precursor for Gold Macro‐Needles Consisting of Gold Nanoparticles Glued by Graphitic Carbon Nitride

“…Comparison of the geometric parameters of the two independent cations reveals that the dithiocarbamate moieties of “Au2” differ significantly from those of “Au1” with respect to the N−C−S angles (Table S3, Supporting Information). We note that the Au−S bond lengths are very similar to those in corresponding cations [Au(S 2 CNR 2 ) 2 ] + , in which Au−S bond lengths are in the range 2.290–2.357 Å, and the geometry of the dithiocarbamate groups (Table S3) is comparable with analogous cations containing the dithiocarbamate group (ibid). Au III is situated in the center of the square planar [AuS 4 ] moiety with D 2 h symmetry, and the diagonal angles are S−Au− S =180°.…”

“…[Au(S 2 CNH 2 ) 2 ]SCN is relatedt oan umber of well-characterized bis(dithiocarbamato)-gold(III) complexes [28][29][30][31][32][33][34][35][36][37][38][39][40][41] with the general composition [Au(ÀS 2 CNR 2 ) 2 ]X (X = halide or complexa nions). The bromide-containing compound [Au(ÀS 2 CNH 2 ) 2 ]Br was prepared earlier, [42] but apart from spectroscopic data, no structural information or detailed properties were mentioned.…”

“…During a long‐time experiment to recrystallize this compound from an acid aqueous solution, partial disproportionation occurred, and several crystals of the new compound [Au(S 2 CNH 2 ) 2 ]SCN were obtained. [Au(S 2 CNH 2 ) 2 ]SCN is related to a number of well‐characterized bis(dithiocarbamato)‐gold(III) complexes with the general composition [Au(−S 2 CNR 2 ) 2 ]X (X=halide or complex anions). The bromide‐containing compound [Au(−S 2 CNH 2 ) 2 ]Br was prepared earlier, but apart from spectroscopic data, no structural information or detailed properties were mentioned.…”

Intramolecular H⋯S interactions in metal di-(isopropyl)dithiocarbamate complexes

“…The N1-C2 and N1-C5 bond lengths are equal within experimental error and all bond lengths are similar to those in other M(dipdtc) structures, where M = Pb, Hg, Ni, In, Co, Be, Cu and Au. [37][38][39][40][41][42][43][44] From the molecular assembly diagram, Fig. 3, a layered supramolecular motif is evident parallel to the crystallographic b direction (see ESI † for images showing packing Fig.…”

Design and synthesis of methyl 2-{[4-phenyl-5-(pyridin-2-yl)-4H-1,2,4-triazol-3-yl]sulfanyl}acetate (phpy2NS) as a ligand for complexes of Group 12 elements: structural assessment and hydrogen-bonded supramolecular assembly analysis

“…Both the Cd-Br t and Cd-Br b bond lengths match well with the corresponding values in hybrid bromidocadmates containing discrete [Cd 2 Br 6 ] 2À anions (Cras et al, 1973;Baby Mariyatra et al, 2002;Lo & Ng, 2009;Lee et al, 2016). The bond angles of the [Cd 2 Br 6 ] 2À anion are in the order (Hines et al, 2006;Zhuang et al, 2009;Hannachi et al, 2010;Kim et al, 2013;Rodina et al, 2012).…”
