Description:
In this work, through the hydrothermal method, two cadmium (II) and two zinc (II) coordination complexes with diverse structural motifs have been synthesized, including [Cd2(HL)I3H2O]*H2O (1), [Cd2(H2L)2(H2O)4]*2SO4*14H2O (2), [Zn3(L')2(H2O)6]*4H2O*2(NO3) (3), and [Zn3L'2(H2O)2Cl2]*H2O (4) (H2L =(1,1-Bis(5-(pyrid-2-yl)-1,2,4-triazol-3-yl)methane; H2L' =(1,1-Bis(5-(pyrid-2-yl)- 1,2,4-triazol-3-yl)methanone). These coordination complexes have been characterized by single crystal X-ray diffraction, powder X-ray diffraction (PXRD), FT-IR and photo-luminescent experiment. Single crystal structural analysis revealed that 1-4 belonged to polynuclear coordination compounds. PXRD analysis of 1-4 unambiguously confirmed the purity of the as-synthesized coordination compounds. It is the first time to synthesize coordination compounds based on H2L' which was from the original material H2L through in-situ hydrothermal condition. In addition, photo-luminescent experiments revealed that 1-4 have real-time sensing effect for benzaldehyde through fluorescence quenching. For 1-4, the photo-luminescent quenching effect for benzaldehyde also have been compared, the coordination complexes 3 and 4 based on H2L' have higher photo-luminescent quenching effect than that of 1 and 2.
