The photoluminescent properties of 17 zinc(II) chelates [Zn(RC(S)NP(C)(OiPr)(2)-0,S)(2)] (R = Ph (1a), PhNH (1b), p-BrPh (1c), p-MeCC6H4NH (1d), p-BrC6H4NH (le), NH2 (1f), iPrNH (1g), tBuNH (1h), Et2N (1i), c-C5H10N (1j), c-OC4HgN (1k), c-C6H11NH (1I), aminobenzo-15-crown-5 (1m)) and [Zn(B) (RC(S)NP(O)(OiPr)(2)-O,S)(2)](R=Ph, B=2,2'-bipyridine (2a); R=Ph, B=1,10-phenanthroline (2b); R = PhNH, B = 2,2'-bipyridine (2c); R = PhNH, B = 1,10-phenanthroline (2d)), are reported. Colorless and air/moisture stable chelate complexes of divalent zinc show blue emission in the solid state when excited with UV light. Complexes If, 1h, 1I were investigated by single crystal X-ray diffraction. The zinc(II) atom in complexes If, 1h, 1I is in a distorted tetrahedral O2S2 environment formed by the C=S sulphur atoms and the P=O oxygen atoms of two deprotonated ligands. (C) 2008 Elsevier Ltd.
