摘要
以3,5-二甲基吡唑和硝酸铜为原料合成三(3,5二甲基吡唑)硝酸铜,并用X-射线单晶衍射方法对其进行了晶体结构解析,结果表明,该化合物的晶胞参数为:a=12.5650(14),b=11.5592(13),c=29.944(3),V=4349.1(8)3,Z=8,Dc=1.454 mg/m3,F(000)=1976,T=293(2)K,R1=0.0618,wR2=0.1601。晶体的空间结构被N-H…O分子间和分子内氢键稳定。
Reaction of 3,5-dimethylpyrazole with copper(Ⅱ) salts yields new mononuclear CuL3(NO3)2 coordination compound,where L-(3,5-dimethylpyrazole).The crystal and molecular structure for the compound was determined by single-crystal X-ray diffraction.The structure is very close to regular square-pyramidal a with CuN3O2 chromophore formed by three L and two NO3-ligands,giving a trigonal distortion parameter(τ)of 0.094.The result showed that the compound was Orthorhombic,Pbca,a = 12.5650(14)?,b = 11.5592(13)?,c = 29.944(3)?,V = 4349.1(8)?^3,Z=8,Dc=1.454 Mg/^m3,F(000)= 1976,T=293(2) K,R1 = 0.0618,wR2 = 0.1601.The complex formed three-dimensional framework through N-H…O intermolecular and intramolecular hydrogen bonds.
