Streszczenie

Structure and magnetic properties of CoII complexes with N-phosphorylthiourea derivatives {RC(S)NHP(O)(OiPr)2} (HL) [Co{Et2NC(S)NP(O)(OiPr)2}2] (1), [Co{iPrNHC(S)NP(O)(OiPr)2}2] (2), [Co{[tBuNHC(S)NP(O)(OiPr)2}2] (3), [Co{p-MeOC6H4NHC(S)NP(O)(OiPr)2}2] (4), [Co{p-BrC6H4NHC(S)NP(O)(OiPr)2}2] (5) were investigated. Paramagnetic shifts in the 1H NMR spectrum were observed for high-spin CoII complexes with HL, incorporating amidophosphate moiety C(S)NP(O). The thermal dependence of the magnetic susceptibility has shown that the extended materials 2, 3 and 5 show ferromagnetic exchange between distorted tetrahedral metal atoms, while in complex 4 antiferromagnetic behavior takes place. Compound 1 behaves as a spin-canted ferromagnet, an antiferromagnetic ordering taking place below a critical temperature, Tc = 175 K. Complex 2 was investigated by single crystal X-ray diffraction. The cobalt(II) atom in complex 2 is in distorted tetrahedral CoO2S2 environment formed by the C=S sulfur atoms and the P=O oxygen atoms of two deprotonated ligands.
