“…[5]. The remaining R 3 PAg(S 2 CNR′R′′) structures have the dithiocarbamate ligands lying to opposite sides of the central Ag 2 S 2 plane [5][6][7][8][9][10][11]. The structure of (I) conforms to the common binuclear structural motif.…”

“…This diversity is evident in the aforementioned Cy 3 PAu(S 2 CNR′R′′) compounds whereby the anti-conformation is formed in the structures with R′ = R′′ = Et and CH 2 CH 2 OH, and R′ = Me, R′′ = CH 2 CH 2 OH but, when NR′R′′ = N(CH 2 )4, the syn conformation is observed [7]. For the general formula, R 3 PAg(S 2 CNR′R′′), in instances when R′ = R′′ = Et and R = Ph and m-tolyl [8], and R 3 P = Ph 2 (2-pyridyl)P [8] and Ph 2 (C5H 3 CN)Fe(C5H4)P [9], the anti-form is observed. Similarly, the anti-conformation is noted in the R = Ph structures with R′ = R′′ = (3-pyridyl) [10], and R′ = CH 2 Ph, R′′ = (3-pyridyl) [10], R′ = Me, R′′ = CH 2 (C5H 3 )Fe(C5H4) [11] and NR′R′′ = N(CH 2 CH 2 )C(H)Me [12].…”

“…The unusual structure was observed when NRR′ = N(CH 2 )4, which has a syn conformation as the dithiocarbamate ligands are orientated to the same side of the Ag 2 S 2 core. The majority of related structures adopt the anti-conformation [6][7][8][9][10][11], with the only other exceptional structure being that of {Ph 2 (Me)PAg(S 2 CNEt 2 )}n, which, although having a similar mode of coordination of the dithiocarbamate ligand, is a one-dimensional coordination polymer in the solid-state [9]. In continuation of studies in this area, herein, the results of the crystal structure determination of {Et 3 PAg[S 2 CN(CH 2 )4]} 2 , (I), are described.…”
