Abstract


Synthesized under normal conditions , one has not been reported polyoxometalate cluster compounds by elemental analysis , IR , TG and single-crystal X- ray diffraction were used to characterize the crystal structures . Compound 1 is based on Anderson structure of multi- anion [ Cr ( OH ) 6Mo6O18 ] 3 - the one-dimensional chain structure compound . Molecular formula : [ Cu ( C10N2H8 ) 2 (H2O ) ] 2 { [ Cu ( C10N2H8 ) ] [ Cr (OH ) 6Mo6018 ] 2 } · 10H20 (1 ) X - ray single crystal diffraction results show that : the compound ( 1) belongs to monoclinic system , P21 / n space group ; unit cell parameters a = 1.4569 ( 2 ) nm , b = 3.4591 ( 5 ) nm , c = 1.5088 ( 2) nm, and α = 90 ° , β = 111.453 ( 2 ) °, γ = 90 °, V = 7.0771 (18) nm3, Z = 4, R1 = 0.0743, ωR2 = 0.1916. The crystal structure analysis showed that the compound is a 1D chain compounds, and are alternately connected to the 2,2 ' - pyridyl complexes of copper and anion [ Cr (OH ) 6Mo6O18 ] 3 - composition . Pyridine ligand π-π interactions between adjacent chains to form a 3D structure . In addition , the acid - based ionic liquid literature research, and possible future development direction .
