Poly[(μ₃-N,N-dibenzyldithiocarbamato-κ⁴S,S′:S:S′)silver(I)]

Abstract

Key indicators: single-crystal X-ray study; T = 293 K; mean (C-C) = 0.014 Å; R factor = 0.045; wR factor = 0.080; data-to-parameter ratio = 14.5.The title Ag I coordination polymer, [Ag(C 15 H 14 NS 2 )] n , was synthesized by a solvothermal reaction of AgNO 3 with sodium N,N-dibenzyldithiocarbamate in a methanol solution. The compound displays a helical structure and each Ag I ion is fourcoordinated by four S atoms from two dithiocarbamate ligands and can be described as a distorted tetrahedral configuration. While the Ag I ions are bridged by both S atoms of the dithocarbamate group to form the polymeric structure, the AgÁ Á ÁAg distance of 3.0633 (11) Å suggests weaker metal bonding between Ag I ions.

On Mono(dithiocarbamato)‐silver(I), AgS2CNH2

“…The crystal structure of Ag 11 S(S 2 CNEt 2 ) 9 consists of a polysilver cluster molecule as characteristic structural feature 8. Further, unexpected structures have been observed in Ag 6 [S 2 CN( n ‐C 4 H 9 ) 2 ] 2 9 with an octahedral hexasilver(I) cluster and in [Ag(S 2 CN R 2 )] n ( R = Bn)10 occurs a one‐dimensional chain‐like coordination polymer with argentophilic interactions. The ample structural variety in this class of silver compounds demonstrates that steric restrictions/demands determine the precise structure.…”

N,N′-Diarylformamidine Dithiocarbamate Ag(I) Cluster and Coordination Polymer

“…Just like in 1, the Ag(I) center is coordinated to three S atoms giving a trigonal p ramidal geometry around the metal center. This differs from the coordination polymer [Ag(dibenzyldithiocarbamate)]∞ [17] where each Ag(I) cation is bonded to two pairs sulfur atoms from three dithiocarbamate ligands resulting in a distorted tetrahedral ometry. The S-Ag-S bond angles range from 102.58(3)°-129.07(4)° and these are sim lar to the ones for coordination polymer of [{Ag(diethyldithiocarbamate)}3]∞ wh ranges from 109.49(4)°-128.56(4)° [24].…”

“…Factors, such as reaction conditions, as well as alkyl substitution effects might be responsible for the formation of a variety of complexes with unprecedented structures [15,16]. In the past decades, monomeric, dimeric, hexameric and polymeric structures have been reported [17].…”

“…Dithiocarbamates have been reported to react with silver(I) ions to form Ag(I) complexes of various geometries [19,20] and also serve as efficient stabilizers for silver nanoparticles [21]. Silver(I) dithiocarbamates, [Ag(S 2 CNR 2 )] n have been known as far back as the 1950s, but little work Molbank 2022, 2022, M1327 2 of 10 had been done on them probably due to their low solubility [17]. They have been widely used as a precursor to acanthite (α-Ag 2 S), a potential material for microelectronics [22,23].…”

“…Yin et al reported the crystal structure of poly [(µ 3 -N,N-dibenzyldithiocarbamatoκ 4 S,S':S:S') silver(I)] [17]. Each Ag(I) cation in this complex was bonded to two pairs of sulfur atoms from three N,N -dibenzyldithiocarbamate ligands, conforming to distorted tetrahedral geometry.…”
