| Abstract: A transition metal complex Zn(mpc)2(H2O)2 (Hmpc=3-methylpyrazole-5-carboxylic acid) has been synth-esized by the reaction of Hmpc with Zn(NO3)2·6H2O using hydrothermal method, which was characterized by IR spe-ctra, elemental analysis and single-crystal X-ray structure analysis. The structure reveals that the complex crystallizes in the trigonal space group R3c with the ZnⅡ atom on a threefold axis, composed of one ZnⅡ atom, two independent mpc- ligands and two coordinated water. Hydrogen bonds link the molecules into a three-dimensional supramolecular architecture. Fluorescent analysis in the dilute EtOH solution shows that the title complex exhibits a broad fluorescent band at 471 nm upon photoexcitation at 280 nm and has a bathochromic shift of the emission energy compared with the free ligand, possibly due to metal-to-ligand charge transfer (MLCT). CCDC: 682402. |
