A new compound 2 6[Co(H 2O) 2(VO) 8(OH) 4(PO 4) 8] has been hydrothermally synthesized. Single crystal X-ray analysis indicates that this compound crystallizes in a monoclinic system, space group P2 1/n with a=1.438 5(3) nm, b=1.012 2(2) nm, c=1.832 5(4) nm, β=90.21°, V=2\^668 2(9) nm 3, Z=2, D c=2.112 g/cm 3, R=0.055, wR=0.149 7, S=1.037. The structure of 2 6[Co(H 2O) 2(VO) 8(OH) 4(PO 4) 8] is characterized by P-V-O layers constructed by [(VO) 4(OH) 2(PO 4) 4] 6- non-symmetric units. The P-V-O layers are pillared by [Co(H 2O) 2] 2+ group, resulting in the channels within which the protonated diaminoethane and H 3O + are located. 展开更多

A new complex[Ni(en) 2V 6O 14] n was hydrothermally synthesized and characterized by 2-dimensional vanadium oxide framework pillared by Ni(en) 2 group. Single crystal X-ray analysis indicates that this compound crystallizes in monoclinic system, space group P2 1/c with a= 0.892 17(18) nm, b= 1.711 1(3) nm, c=0.662 73(13) nm, β=111.58(3)°, V=0.940 8(3) nm 3, Z=2, D c= 2.501 g/cm 3, R=0.042 3, wR=0.060 9, S=1.006. 展开更多
