Complexes of crown ether-containing N-phosphorylated thioamides and thioureas with CoII, ZnII and PdII cations

Abstract

The reaction of the potassium salts of N-phosphorylated thioureas [4'-benzo-15-crown-5]NHC(S)NHP(Y)(OiPr)2 (Y = S, HLI; Y = O, HLII) with ZnII and CoII cations in aqueous EtOH leads to complexes of formulae Zn(LI,IIS,Y)2 (Y = S, 1; Y = O, 2) and Co(LIS,S')2 (3), while interaction of the potassium salt of N-phosphorylated thioamide [4'-benzo-l5-crown-5]C(S)NHP(O) (OiPr)2 (HLIII) with ZnII in the same conditions leads to the complex Zn(HLIII)(LIII-S,O) 2 (4). The reaction of the potassium salt of crown ether-containing N-phosphorylated bis-thiourea N,N'-[C(S)NHP(O)(OiPT)2] 2-1,10-diaza-18crown-6 (H2L) with CoII, Zn.II and PdII cations in anhydrous CH3OH leads to complexes M2(L-O,A)2 (M = Co, 5; Zn, 6; M = Pd, 7). Thioamide HLIII was investigated by single-crystal X-ray diffraction. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
