Decavanadium oxide [Co 2Cl 8V 10 O 18 (H 2O)]Cl 2·6H 2O was synthesized hydrothermally with NH 4VO 3, Na 2MoO 4·2H 2O, H 3PO 4(85%), CoCl 2·6H 2O and hexamethylenetetraamine. The X ray diffraction analysis showed that [Co 2Cl 8V 10 O 18 (H 2O)]Cl 2·6H 2O crystallized in a monoclinic crystal system, the space group was C2/m with cell parameters a =1 6065(3) nm, b =2 2699(5) nm, c =1 3897(3) nm, β = 125.29(3)°, V =4 1363(14) nm 3, Z =2 and the final R =0 06, wR =0 1926. Its crystal structure is a 3 D open framework constructed by VO x polyhedra and CoCl 4 tetrahedra with channels along the crystallographic axes a, b, and c .
