Complexes of crown-containing N-thioacylamido(thio)phosphates with Zn(II) and Co(II) cations

Abstract

Reaction of the potassium salts of N-acylamido(thio)phosphates [4′-benzo-15-crown-5]NHC(S)NHP(Y)(OiPr)2 (Y = S, HLI; Y = O, HLII) with Zn(II) and Co(II) cations in aqueous EtOH leads to complexes of formulae Zn(LI,II - S,Y)2 (Y = S, 1; Y = O, 2) and Co(LI-S,S′)2 (3), while interaction of the potassium salt of [4′-benzo-15-crown-5]C(S)NHP(O)(OiPr)2 (HLIII) with Zn(II) in the same conditions leads to a complex of composition Zn(HLIII)(LIII-S,O)2 (4). © 2006 Elsevier B.V.
