Compound [V_ 16 O_ 38 (Cl)][Cu(enMe)_2]_ 3.5 ·2H_2O(1) has been hydrothermally synthesized and characterized by means of single-crystal X-ray diffraction,elemental analysis,IR,EPR and TGA analysis. The X-ray crystallography shows that compound 1 contains a new {V_ 16 O_ 38 } cluster shell,which is connected by [Cu(enMe)_2] 2+ coordination fragments into a 3-D framework. The compound crystallized in a monoclinic system with space group P2(1)/n,M =2235.82,a =1.26076(3) nm,b =2.55802(6) nm,c =2.14742(4) nm,β =90.7380(10)°, V =6.9250(3) nm 3,Z =4,F (000)=4418,D _c=2.145 g·cm -3 , μ =3.227 mm -1 ,( Δ/σ )=0.000,S =1.066. 展开更多

A novel compound [H_2Mo_ 5.5V_ 10.5O_ 40(PO_4)][Cu(en)_2]_4·7H_2O(1) was synthesized from V_2O_5, MoO_3, CuCl_2·2H_2O, en, H_3PO4 and H_2O in an aqueous solution via the hydrothermal method and characteri... A novel compound [H_2Mo_ 5.5V_ 10.5O_ 40(PO_4)][Cu(en)_2]_4·7H_2O(1) was synthesized from V_2O_5, MoO_3, CuCl_2·2H_2O, en, H_3PO4 and H_2O in an aqueous solution via the hydrothermal method and characterized by means of single-crystal X-ray diffraction, elemental analyses, IR, EPR spectra and thermal analyses. C_ 16H_ 80Cu_4Mo_ 5.5N_ 16O_ 51PV_ 10.5 crystallized in a triclinic system, the space group is P1 with M=2660.63, a= 1.283590(10) nm, b=1.289910(10) nm, c=1.387870(10) nm, V=1.80942(2) nm 3, Z=2, D_x=4.883 g/cm 3, F(000)=2599, μ=6.956 mm -1, (Δ/σ)=0.000, S=1.089. The crystal structure was solved by the direct methods with the final R=0.0752 and wR=0.1988 for 6311 observed reflections with I≥2σ(I). The X-ray crystallography reveals that compound 1 is a novel two-dimensional framework material constructed from the mixed Mo/V polyoxometalate and coordination groups. 展开更多
