Complexes of Crown Ether‐Containing N‐Phosphorylated Thioamides and Thioureas with CoII, ZnII and PdII Cations

Abstract

AbstractThe 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,II‐S,Y)2 (Y = S, 1; Y = O, 2) and Co(LI‐S,S′)2 (3), while interaction of the potassium salt of N‐phosphorylated thioamide [4′‐benzo‐15‐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)(OiPr)2]2‐1,10‐diaza‐18‐crown‐6 (H2L) with CoII, ZnII and PdII cations in anhydrous CH3OH leads to complexes M2(L‐O,S)2 (M = Co, 5; Zn, 6; M = Pd, 7). Thioamide HLIII was investigated by single‐crystal X‐ray diffraction.
