Syntheses and structures of two organic-inorganic hybrid vanadates, [Cu(1,10-phenanthroline)(H2O)V2O6] and [Co(1,10-phenanthroline)(H2O)V2O6]

摘要

Two new organic-inorganic hybrid vanadates, [Cu(1,10-phenanthroline)(H2O)V2O6] (1) and [Co(1,10-phenanthroline)(H2O)V2O6] (2) were synthesized hydrothermally. The cell parameters of the compounds are: 1, a = 7.8353(5), b = 9.2300(6), c = 10.7162(7) Angstrom, alpha = 88.830(1), beta = 70.891(1), gamma = 76.444(1)degrees, V = 710.55(8) Angstrom(3), Z = 2 and 2, a = 7.8357(4), b = 21.0896(12), c = 9.415 5(5) Angstrom, beta = 11 2.904(1), V= 143 3.26(13) Angstrom(3), Z = 4. Compound 1 is one-dimensional consisting of [V4O12](4-) rings connected through [Cu(phen)(H2O)](2+) subunits. The structure of 2 is two-dimensional, with a network constructed from one-dimensional chains of corner-sharing [VO4](3-) tetrahedra, which are linked through [Co(phen)(H2O)](2+) groups.
