以4,4′-H2bpz （L=4,4′-H2bpz=3,3′，5,5′-四甲基-4,4′-联吡唑）和ag4p2o7为原料，在水热条件下自组装合成了3-连接的双f型金属-有机骨架化合物{[Ag(L)3/ 2h2po4]}n(1)。结晶在四方空间群I41/ add中，a=21.406(4)Å， b=21.406(4)Å， c=36.298(8)Å， Z=32。x射线单晶衍射显示，1具有前所未有的左、右手交替螺旋结构的三维框架，具有不均匀的双重互穿（4.142）网。光致发光研究表明，标题化合物在广泛的区域内显示出有趣的发射，这表明标题化合物可能是一个很好的光电材料候选者。
A 3-connected dia-f-type metal-organic framework compound {[Ag(L)3/2H2PO4]}n(1) has been synthesized by self-assembly of 4,4′-H2bpz (L=4,4′-H2bpz=3,3′,5,5′-tetramethyl-4,4′-bipyrazole) and Ag4P2O7under hydrothermal conditions. It crystallizes in the tetragonal space group I41/acd with a=21.406(4)Å, b=21.406(4)Å, c=36.298(8)Å, Z=32. X-ray single-crystal diffraction reveals that 1 has a three-dimensional framework with an unprecedented alternate left- and right-handed helices structure, featuring a non-uniform two-fold interpenetrated (4.142) net. Photoluminescent investigation reveals that the title compound displays interesting emissions in a wide region, which shows that the title compound may be a good potential candidate as a photoelectric material.
