利用溶剂热法合成了2种新的有机杂化锑硒化合物[Ni(dap)3]2(Sb2Se5)].2H2O(1)和[Zn(dap)3]2(Sb2Se5)](2)(dap=1,2-丙二胺),单晶X射线衍射分析结果表明,1属于三方晶系,P3121空间群,晶胞参数为a=10.7574(14),b=10.7574(14),c=31.672(4),γ=120.00°,z=4。2属于单斜晶系,P21空间群,晶胞参数为a=10.772(2),b=16.391(3),c=11.704(2),β=100.912(4)°,z=4。在2种化合物中,Ni2+与Zn2+离子分别与3个dap配体螯合形成畸变八面体几何构型,其中dap配体的N原子是无序的,而二聚[Sb2Se5]2-阴离子是由2个SbSe3三角锥共用1个Se原子连接而成。
Two new organic hybrid antimony selenides [Ni (dap) 3] 2 (Sb2Se5)] 2H2O (1) and [Zn (dap) 3] 2 (Sb2Se5)] (2) were synthesized by solvothermal method dap = 1,2-propanediamine). The results of single crystal X-ray diffraction analysis showed that 1 belongs to the trigonal system with P3121 space group and the unit cell parameters are a = 10.7574 (14), b = 10.7574 31.672 (4), γ = 120.00 °, z = 4.2 belong to the monoclinic system P21 space group with unit cell parameters of a = 10.772 (2), b = 16.391 (3) and c = 11.704 β = 100.912 (4) °, z = 4. Among the two compounds, Ni2 + and Zn2 + ions chelate with three dap ligands respectively to form a distorted octahedral geometry, in which the N atom of the dap ligand is disordered and the dimeric [Sb2Se5] 2- anion is formed from Two SbSe3 triangular pyramids share one Se atom.
