摘要：

Two novel coordination compounds, namely, [Sm-2(pypza)(2)(H2O)(10)]Cl-4 center dot H2O (1) and [Eu(pypza)(C2O4)] (2), where pypza = 3-(2-pyridyl)-1-pyrazolyl acetato, have been synthesized under hydrothermal conditions. These compounds were characterized by elemental analysis, infrared spectroscopy, and single-crystal X-ray diffraction. The X-ray diffraction analysis reveals that compound 1 displays double one-dimensional chains, whereas 2 shows a two-dimensional layer structure via the bridging pypza and oxalate (C2O42-) which may arise from the oxidation of hydroacetic acid through the decomposition and hydrolysis of Hpypza by means of the cleavage of the C-N bond between the carboxylate group and the pyrazolyl ring. Compounds 1 and 2 show three-dimensional networks by hydrogen bonding interactions. Furthermore, the luminescence properties of 1 and 2 have also been investigated at room temperature in the solid state.
