Complexes of Crown Ether‐Containing N ‐Phosphorylated Thioamides and Thioureas with Co II , Zn II and Pd II Cations

The reaction of the potassium salts of N ‐phosphorylated thioureas [4′‐benzo‐15‐crown‐5]NHC(S)NHP(Y)(O i Pr) 2 (Y = S, HL I ; Y = O, HL II ) with Zn II and Co II cations in aqueous EtOH leads to complexes of formulae Zn(L I,II ‐ S,Y ) 2 (Y = S, 1 ; Y = O, 2 ) and Co(L I ‐ S , S′ ) 2 ( 3 ), while interaction of the potassium salt of N ‐phosphorylated thioamide [4′‐benzo‐15‐crown‐5]C(S)NHP(O)(O i Pr) 2 ( HL III ) with Zn II in the same conditions leads to the complex Zn(HL III )(L III ‐ S,O ) 2 ( 4 ). The reaction of the potassium salt of crown ether‐containing N ‐phosphorylated bis‐thiourea N , N′ ‐[C(S)NHP(O)(O i Pr) 2 ] 2 ‐1,10‐diaza‐18‐crown‐6 ( H 2 L ) with Co II , Zn II and Pd II cations in anhydrous CH 3 OH leads to complexes M 2 (L‐ O,S ) 2 (M = Co, 5 ; Zn, 6 ; M = Pd, 7 ). Thioamide HL III was investigated by single‐crystal X‐ray diffraction.
