Synthesis and spectral studies of some new palladium(II) and platinum(II) dithio complexes: The novel crystal structure of the palladium(II) dithiocarbimato complex

The Coordination Chemistry of Imidomethanedithiolate Di-anions: A Structural Comparison with Their Dithiocarbamate Analogs

“…c S-stereoisomer. Two di-anionic palladium(II) complex molecules adopt the square planar motif illustrated in Figure 6a: {Pd[S2C=N(CN)]2} 2− in 13 [19] and {Pd[S2C=N(C6H4NH2-4)]} 2− in 14 [23]. The palladium atoms in the two independent di-anions in the asymmetric unit of 13 and in the di-anion in 14 are each located on a center of inversion.…”

“…Another general procedure for the formation of dithiocarbimate complexes involves the conversion of a pre-formed dithiocarbamate complex to the dithiocarbimate derivative. As an example of this method, [NBu 4 ] 2 {Pd[S 2 C=N(C 6 H 4 NH 2 -4)] 2 } [23] was prepared from the reaction of Pd[S 2 CN(H)C 6 H 4 NH 2 -4] 2 with excess NaOH, whose function is to abstract the S 2 CN-bound proton from the dithiocarbamate complex, followed by the addition of tetrabutylammonium bromide to yield the dithiocarbimate complex.…”
