摘要
合成和表征了一个新的氧钒配合物[VO2(Sal)(Phen)]·H2O.在该配合物中,钒(V)原子与六个氧原子配位,形成一个变形的八面体结构.该晶体属于单斜晶系,空间群为C2/c.晶胞参数为a=3.0857(9)nm,b=0.7256(2)nm,c=2.0470(6)nm,β=127.413(4)°,V=3.6407(19)nm3,Z=8,Dc=1.468g·cm-3,F(000)=1648,R1=0.0772,wR2=0.1067.在晶体结构中,分子间氢键和π-π堆积使晶体构成了一个三维网状结构.
The new vanadyl complex [VO2 (Salicylaldehyde)(Phenanthroline)] · H2O was synthesized and characterized by IR, elemental analysis and X-ray diffraction analysis. In the complex, the vanadium atom (V) was coordinated to six oxygen atoms and formed a distorted octahedral structure. The crystal belonged to monoclinic system with space group C2/c,a =3. 085 7(9) nm,b =0. 725 6(2) nm,c = 2. 047 0(6) nm,β=127.413(4)°,γ=3.6407(19)nm^3,Z=8,Dc=1.468g·cm^-3,F(000)=1648,R1=0.0772,ωR2=0.1067.In the crystal structure, the combination of intermoleeular hydrogenbonding (O-H...O) and π-π stacking interactions resulted in the three-dimensional network structure.
