摘要

A novel lanthanum-molybdenum coordination polymer [La(H2O)(3)(MoO4)](2)C2O4 (1) has been synthesized from hydrothermal reactions. Single crystal structure analysis reveals that compound 1 has a 3D framework structure consisting of double-metal centers of nine-coordinated La(III) and four-coordinated Mo(VI), and bridging oxalate ligands (C2O42-). Interestingly, in situ formation of ligand from L-Histidine to oxalate is observed. Furthermore, the fluorescence property of the polymer has also been investigated.
