What is Hydrothermal synthesis and characterization of metavanadate containing spiral chain: Ni(en)3(VO3)2 about?
The hydrothermal reaction of V 2 O 5 , NiCl 2 •6H 2 O, ethylenediamine and H 2 O in the mole ratio 1:1:4.9:120 at 150°C for 55 h produced violet prismatic crystals of Ni(en) 3 (VO 3 ) 2 . The crystal of the title compound is hexagonal P6 1 , a=8.986(1), c=34.031(2) A , , V =2379.8(5) A , 3 , Z=6, D calc =1.829 g cm -3 and R= 0.0609 for 1406 observed reflections. The structure of Ni(en) 3 (VO 3 ) 2 consists of spiral anion (VO 3 ) chains formed by corner-sharing VO 4 tetrahedra with Ni(en) 3 2 + complex cations occupying the interchain positions, where there are electrostatic interactions and hydrogen bonds between the anion chain and the complex cation. The title compound is the first example of a vanadium compound, in which the repeat unit of the chain is 12-nuclear corner-sharing tetrahedra, V 12 O 36 . The magnetic susceptibility of the title compound has been studied.
