Abstract:

Three novel vanadium selenites with the formulae [(VO2)(1,10-phenanthroline)(SeO3H)](2) 1, [(VO2)(2,2'-bipyridine)](2)(SeO3) 2 and [(VO)(H2O)(SeO3)(2)](2)(H4EDD) 3 (EDD = N1,N1'-(ethane-1,2-diyl)diethane-1,2-diamine) were hydrothermally synthesized, and characterized with elemental analysis, FT-IR spectrum, Raman spectrum, TG-DTA analysis, EPR spectra, and single-crystal X-ray diffraction analysis. Compound 1 belongs to the triclinic system, space group P (1) over bar with a = 7.7527(5), b = 9.5345(10), c = 9.8192(8) angstrom, alpha = 92.712(3), beta = 105.540(3), gamma =108.154(4)degrees, V = 657.66(1) angstrom(3), M-r = 782.22, Z = 1, F(000) = 384, mu(MoK alpha) 3.544 mm(-1), R = 0.0432 and wR = 0.1142; Compound 2 is of orthorhombic system, space group P2(1)2(1)2(1) with a = 7.6574(15), b = 14.916(3), c = 19.085(4) angstrom, V = 2179.8(8) angstrom(3), M-r = 605.21, Z = 4, F(000) = 1200, mu(MoK alpha) = 2.579 mm(-1), R = 0.0338 and wR = 0.0658; Compound 3 belongs to the triclinic system, space group P (1) over bar with a = 9.247(2), b = 9.659(2), c = 7.2651(19) angstrom, alpha = 98.171(7), beta = 103.709(5), gamma = 114.712(13)degrees, V = 550.9(2) angstrom(3), M-r = 828.03, Z = 1, F(000) = 400, mu(MoK alpha) = 7.537 mm(-1), R = 0.0641 and wR = 0.2118. Compound 1 is constructed from alternating corner-shared [VO4N2] octahedra and SeO3H units, forming a dimeric vanadium unit. These assemblies are further linked into an infinite chain via hydrogen bonds along the a axis. In the structure of 2, two distinct V centers form centrosymmetric [V2O6N4] clusters through edge-sharing, and the SeO3 unit serves as a capping unit to fix the oxovanadate cluster. In the structure of 3, each [VO6] octahedron shares four oxygen atoms with adjacent Se atoms, while every SeO3 unit shares two oxygen atoms with neighboring V atoms. This connectivity of alternating VO6 and SeO3 units results in a joint-like chain. Based on the TGA analysis, these three compounds are thermally stable under 200 degrees C.
