摘要
本文采用中温水热方法合成了具有二维层状结构的无机有机杂化材料{Cu(phen)H2O}{Cu(phen)}V4O7(OH)(PO4)3H2O(1,phen=邻菲啰啉),并由X射线单晶衍射分析确定了它们的晶体结构.配合物1属于三斜晶系,P-1空间群,晶胞参数:a=0.743 31(15)nm,b=1.158 1(2)nm,c=2.076 8(4)nm,α=87.56(3)°,β=82.44(3)°,γ=73.37(3)°,V=1.698 1(6)nm3,Z=2,R(int)=0.273,R1=0.083 4,wR2=0.229 5.配合物1中Cu中心呈现四方锥和平面四方两种配位模式,钒为常见的1+4+1八面体.钒原子形成V4O4立方簇,Cu-O-P连接形成左手和右手螺旋链,结构独特.
A novel 2-dimensional Cu-V inorganic-organic hybrid polyoxovanadate, Cu (phen) H2O {|Cu (phen) } -V4O7 (OH) ( PO4) 3 H2O ( 1, phen = o-phenanthroline) , was synthesised and characterized by X-ray diffraction. The complex crystallized in the triclinic space P-1 with α= 0. 743 31 (15) nm, b = 1. 158 1 (2) nm, c = 2. 076 8 (4) nm,α=87.56(3)°,β =82.44(3)°,γ=73.37(3)°,V= 1. 698 1(6) nm^3,Z =2,R(int) =0. 273,R1 =0. 083 4, wR2 = 0. 229 5. In complex 1 two independent Cu atoms present two kind of coordination geometries, square pyramid and square plane. There is a V4O4 cubic cluster and left and right helical chains in complex 1. The structure is unique.
