以硅钨酸、4，4 ′-H2 bpz（L = 4，4 ′-H2 bpz = 3，3 ′，5，5 ′-四甲基取代的4，4 ′-联吡唑）和AgF为原料，水热合成了一种新的红外非线性光学化合物[（Ag 4L 4）（SiW 12 O 40）]。它的结构由罕见的（AgL）∞城堡链组成，这些链由聚氧乙烯簇连接，形成有趣的二维3重互穿结构。标题化合物是第一个含多金属氧酸盐的金属-有机混合化合物的例子，已被证明在IR区域具有强的SHG效应，并且在高达约100 ℃的温度下热稳定。400 °C。
A new IR non-linear optical compound [(Ag4L4)(SiW12O40)] has been hydrothermally synthesized from the self-assembly of silicotungstic acid, 4,4′-H2bpz (L = 4,4′-H2bpz = 3,3′,5,5′-tetramethyl-substituted 4,4′-bipyrazole) and AgF. Its structure is composed of rare (AgL)∞ castellated chains that are linked by polyoxometalate clusters to form an interesting two dimensional 3-fold interpenetrated structure. The title compound is the first example of a polyoxometalate-containing metal–organic hybrid compound that has been shown to have strong SHG effect in IR region and is thermally stable up to ca. 400 °C.
