摘要
A new polyoxomolybdate compound [Mn II （L） 2 （Mo 8 O 26） 0.5 ] 2n （1,L=3-（2-pyridyl）pyrazole） has been hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction,elemental analyses,TG and IR spectroscopy.The compound crystallizes in the triclinic system,space group P1 with a=10.063（4）,b=11.554（5）,c=11.554（5）,α=88.89,β=74.839（4）,γ=74.839（4）o,V=1249.8（9） 3,C 16 H 14 MnMo 4 N 6 O 13,M r=937.03,D c=2.490 g/cm 3,μ（MoKα）=2.521 mm 1,F（000）=898,Z=2,the final R=0.0390 and wR=0.0970 for 4000 observed reflections （I 2σ（Ⅰ））.Single-crystal X-ray diffraction analysis results reveal that compound 1 owns a chain structure based on β-[Mo 8 O 26 ] 4anions,which are linked by Mn II （L） 2 units via the terminal oxygen atoms.
