Abstrakt: The reaction of the potassium salt of the N-(thio)phosphorylated thioureas AdNHC(S)NHP(O)(OiPr)2 (HLI, Ad = Adamantyl) and MeNHC(S)NHP(S)(OiPr)2 (HLII) with Co(II) and Zn(II) in aqueous EtOH leads to [MLI,II2] chelate complexes. They were investigated by UV-vis, 1H and 31P NMR spectroscopy, and microanalysis. The molecular structures of [MLI2] were elucidated by single crystal X-ray diffraction analysis. The metal centers in both complexes are found to be in a distorted-tetrahedral O2S2 environment formed by the C=S sulfur atoms and the P=O oxygen atoms of two deprotonated LI ligands. The photoluminescence properties of [ZnLII2] are also reported. [ABSTRACT FROM AUTHOR]
