Solution and mechanochemical syntheses, and spectroscopic and structural studies in the silver(i) (bi-)carbonate : triphenylphosphine system

Syntheses of a number of adducts of silver(I) (bi-)carbonate with triphenylphosphine, both mechanochemically, and from solution, are described, together with their infra-red spectra, (31)P CP MAS NMR and crystal structures. Ag(HCO(3)):PPh(3) (1 : 4) has been isolated in the ionic form [Ag(PPh(3))(4)(HCO(3))center dot 2EtOH center dot 3H(2)O. Ag(2)CO(3):PPh(3) (1 : 4) forms a binuclear neutral molecule [(Ph(3)P)(2)Ag(O,mu-O'center dot CO)Ag(PPh(3))(2)](center dot 2H(2)O), while Ag(HCO(3)):PPh(3) (1 : 2) has been isolated in both mononuclear and binuclear forms: [(Ph(3)P)(2)Ag(O(2)COH)] and [(Ph(3)P)(2)Ag(mu-O center dot CO center dot OH)(2)Ag(PPh(3))(2)] (both unsolvated). A more convenient method for the preparation of the previously reported copper(I) complex [(Ph(3P))(2)Cu(HCO(3))] is also reported
