  Synthesis and structural characterization of adducts of silver (I) diethyldithiocarbamate with P-donor ligands

  摘要：

  Adducts of triorganophosphines PR3, and diphosphines R2P(CH2)(n)PR2 with silver(I) diethyldithiocarbamate Ag(dtc) have been synthesized and characterized both in solution (H-1, P-31 NMR) and in the solid state (IR, single-crystal X-ray structure analysis). The topology of the structures in the solid state was found to depend on the nature of the P-donor and on the Ag(dtc):P-donor stoichiometric ratio. In the mononuclear [(Ph2MeP)(2)Ag(dtc)] and [{(:CH.PPh2)(2)}Ag(dtc)], four-coordinate P2AgS2 environments are found, as also in [(dtc)Ag(P'-dppm-P')(2)Ag(dtc)] where the two Ag(dtc) moieties are linked by the pair of bidentate, bridging, dppm ligands; by contrast the dppp adduct Ag(dtc):dppp (1:1) is an infinite one-dimensional polymer. In the other complexes [(R3P)Ag(dtc)](2) structurally defined, the silver environment is PAgS3, two of the sulfur atoms drawn from the same dtc, now an unsymmetrical chelate, and one of the sulfur atoms bridged to the second silver atom.

  Silver(I), being a soft acid shows a preference for P and S containing ligands. In the present study, simple and mixed ligand complexes of Ag(I) involving mono- and diethanoldithiocarbamates, Ag(MEADTC) and Ag (DEADTC), with triphenylphosphine and 1,2-bis(diphenylphosphino)ethane (diphos) were synthesized. For a comparison, Ag(DEDTC), the diethyl analogue, was also synthesized and the properties studied with IR, UV-visible, TG, DT techniques. The mixed ligand complexes involving PPh(3) and diphos viz., Ag(DEDTC)(PPh(3))(2), Ag(DEDTC)(diphos), Ag(DEADTC)(PPh(3))(2) and Ag(DEADTC)(diphos) (DEDTC(-) diethyldithiocarbamate anion, DEADTC(-) = diethanoldithiocarbamate anion) showed very low conductivity indicating non-ionic character and ruled out possible ion pair formation such as [(PPh(3))(2)Ag](+)DEDTC(-) or [(diphos)Ag](+)DEDTC(-) proposed earlier. In addition, the isolated Ag(MEADTC) complex was found to be highly unstable and, hence, an equilibrium study was made and the stability constant was determined to be 6.1 +/- 0.2 by the Harvey and Manning method.
