摘要
标题化合物Ni(C_3H_2N_3O_3)_2(H2O)_4属正交晶系,空间群为Fmmm(编号69)。晶胞参数:a=7.282(4),b=12.057(2),c=16.072(2),V=1411(1),D_c=1.82g/cm ̄3,Z=4,M_r=386.89,λ(MoKα)=0.71069,μ=14.43cm ̄(-1),F(000)=792。最终偏离因子R=0.045,R_w=0.060。独立可观测点数(I≥3σ(I))为385个。在配合物中,镍离子与来自氰尿酸的两个氮原子和来自水分子的四个氧原子配位。
The Crystal structure of the title compound belongs to the orthorhombic system. Space group Fmmm(#69),with cell parameters:a=7.282(4),b=12.057(2),c= 16. 072(2) ,V= 1 41 1 (1) ,D_c =1.82 g/cm ̄3,Z=4,M_r =386.89,λ(MoKα) =0.71069,μ = 14. 43cm ̄(-1) ,F(000) = 792,final R = 0. 045 and R_w=0. 060 for 385 observable reflections with I≥3σ(I). In the complex Ni (C_3H_2N_3O_3)_2 (H_2O)_4,the Ni ̄(2+) is coordinated by two nitrogen atoms from cyanuric acid ligands and four oxygen atoms from water molecules.
