摘要
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.
