摘要
A new polyoxomolybdate compound [Ag 3 （HL） 4 ]（PMo 12 O 40）] 1 （HL=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 triclinic,space group P1 with a=10.375（3）,b=12.076（3）,c=13.196（4）,α=84.170（4）,β=71.961（3）,γ=86.326（4）°,V=1563.1（7）3,C 32 H 28 Ag 3 Mo 12 N 12 O 40 P,M r=2726.52,D c=2.897 g/cm 3,μ（MoKα）=3.366 mm 1,F（000）=1284,Z=1,the final R=0.0587 and wR=0.1312 for 4139 observed reflections （I 2σ（Ⅰ））.X-ray diffraction analyses reveal that the PMo 12 O 40 3clusters in compound 1 are linked by four Ag 3 （HL） 4 3＋ units via the terminal oxygen atoms to form a two-dimensional architecture.The symmetrical unit of Ag 3 （HL） 4 3＋ exhibits two distinct Ag（Ⅰ） environments：a two-coordinate {AgN 2 } site and a five-coordinate {AgN 3 O 2 } site which links to two molybdate clusters.
