Na2 MoO4 ·2H2 O和 2 氯甲基吡啶在水中反应得到了超分子化合物 :[MoO2 (OCH2 C5H4 N) 2 ].其单晶结构测试表明 :该化合物含有两种均为 6配位的但化学环境不同的Mo(1)和Mo(2 )原子 ;由此两种钼原子构成的中性配合物[Mo(1)O2 (OCH2 C5H4 N) 2 ]和 [Mo(2 )O2 (OCH2 C5H4 N) 2 ]分别通过氢键O…H—C及吡啶环间的π π堆积作用形成了二维的A层和B层 ,A层与B层之间又在层间氢键的作用下交错形成了三维的网状固态结构 .用Z scan法在DMF溶液中测试了该化合物的三阶非线性光学性能 ,发现它有强的非线性吸收 (α2 =1 92× 10 -9m·W-1)和强的非线性折射 (n2 =9 5 2× 10 -19m2 ·W-1) ,非线性极化率 χ( 3 ) =1 2 1× 10 -12 esu .
The reaction of Na2 MoO4 · 2H2O and 2-chloromethylpyridine in water gave the supramolecular compound [MoO2 (OCH2 C5H4N) 2] .The single crystal structure of the compound showed that the compound contains two kinds of coordination compounds Mo (1) O (OCH2C5H4N) 2] and [Mo (2) O2 (OCH2C5H4N) 2, ) 2] formed a two-dimensional A-layer and a B-layer through the hydrogen bonds O ... H-C and π π stacking between the pyridine rings, respectively, and the layer A and the layer B were interlaced by inter-layer hydrogen bonding Dimensional three-dimensional network structure was obtained.The third-order nonlinear optical properties of the compound were tested by Z-scan method in DMF solution and found to have strong nonlinear absorption (α2 = 1 92 × 10 -9 m · W -1) And strong nonlinear refraction (n2 = 9 5 2 × 10 -19m2 · W-1), the nonlinear polarizability χ (3) = 1 2 1 × 10 -12 esu.
