A new homochiral ligand,(R)-2-(4-pyridyl)-4,5-dihydrothiazole-4-carboxylic acid(HL~R), has been synthesized. Two complexes, [ZnL_2~R(H_2O)_2]?H_2O(1) and [MnL_2~R(H_2O)_2]?H_2O(2) have been prepared by the reactions of Zn(Ⅱ) and Mn(Ⅱ) ions with the ligand HLR, and characterized by single-crystal X-ray diffraction analysis and fluorescence. Complexes 1 and 2 are isomorphs, and both of the Zn(Ⅱ) and Mn(Ⅱ) centers in 1 and 2 are six-coordinated by the two NO units of two ligands and two water oxygen atoms, showing distorted octahedral coordination geometry. Complexes 1 and 2 show fluorescent properties in the solid state at room temperature.
A new homochiral ligand, (R) -2- (4-pyridyl) -4,5-dihydrothiazole-4-carboxylic acid (HL ~ R), has been synthesized. Two complexes, [ZnL_2 ~ R (H_2O) _2] H_2O (1) and [MnL_2 ~ R (H_2O) _2] ~ H_2O (2) have been prepared by the reactions of Zn (Ⅱ) and Mn (Ⅱ) ions with the ligand HLR, and characterized by single- diffraction analysis and fluorescence. Complexes 1 and 2 are isomorphs, and both of the Zn (II) and Mn (II) centers in 1 and 2 are six-coordinated by the two NO units of two ligands and two water oxygen atoms, showing distorted octahedral coordination geometry.
