Reaction of the potassium salts of N-thiophosphorylthioureas RC(S)NHP(S)(OiPr)2 (R = MeNH, HLI; 2-MeC6H4NH, HLII; 2,6-Me2C6H3NH, HLIII; 2,4,6-Me3C6H2NH, HLIV; 2-Py(6-Me)NH, HLV) with Zn(II) and Cd(II) in aqueous EtOH leads to the complexes [Zn(LI–V-S,S′)2] ([ZnLI–V2]) and [Cd(LI–V-S,S′)2] ([CdLI–V2]). Reaction of the potassium salt KLV with Ni(II) in aqueous EtOH leads to the complex [Ni(2-Py(6-Me)NHC(S)NP(S)(OiPr)2-N(Py),N(P),S)2] ([NiLV2]), where the metal cation is coordinated by two deprotonated ligands LV through the pyridine and phosphorylamide nitrogen atoms, and the PS sulfur atoms. The structures of the new complexes were studied by NMR spectroscopy; their compositions were examined by microanalysis. The molecular structure of [ZnLV2] was elucidated by single crystal X-ray diffraction. The metal center is found in a tetrahedral S4 environment formed by the CS and PS sulfur atoms of two deprotonated ligands LV. The colorless and air/moisture stable chelate complexes of divalent zinc and cadmium show blue emission in the solid state when excited with UV light.
