Abstract

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, P-31 CP MAS NMR and crystal structures. Ag(HCO3):PPh3 (1 : 4) has been isolated in the ionic form [Ag(PPh3)(4)(HCO3)center dot 2EtOH center dot 3H(2)O. Ag2CO3:PPh3 (1 : 4) forms a binuclear neutral molecule [(Ph3P)(2)Ag(O,mu-O'center dot CO)Ag(PPh3)(2)](center dot 2H(2)O), while Ag(HCO3):PPh3 (1 : 2) has been isolated in both mononuclear and binuclear forms: [(Ph3P)(2)Ag(O2COH)] and [(Ph3P)(2)Ag(mu-O center dot CO center dot OH)(2)Ag(PPh3)(2)] (both unsolvated). A more convenient method for the preparation of the previously reported copper(I) complex [(Ph-3P)(2)Cu(HCO3)] is also reported.
