Abstract
A novel diperoxovanadate complex NH(4)[OV(O(2))(2)(picolinamide)].H(2)O was synthesized from aqueous solution under physiological conditions. The solution structure of the complex was characterized by multinuclear ((1)H, (13)C, (14)N, and (51)V), variable temperature as well as two-dimensional (DOSY) NMR techniques in the interaction system of NH(4)VO(3)/H(2)O(2)/picolinamide at room temperature. The crystal structure of the complex was determined at 223K by single-crystal X-ray diffraction method. It belongs to the monoclinic space group P21/c with a=7.323(3)A, b=14.255(7)A, c=10.022(5)A, beta=99.524(9) degrees , V=1031.7(8)A(3), and Z=4. The crystal is composed of ammonium ions, picolinamide oxodiperoxovanadate(V) ions, and water molecules, which are held together by ionic and hydrogen bond forces. The species [OV(O(2))(2)(picolinamide)](-) is seven-coordinated with a distorted pentagonal bipyramidal geometry both in solution and in crystal.

PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2008; 71:644-649. [PMID: 18304861 DOI: 10.1016/j.saa.2008.01.019] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/20/2007] [Revised: 01/06/2008] [Accepted: 01/12/2008] [Indexed: 05/26/2023]
Abstract
To understand the substituting group effects of organic ligands on the reaction equilibrium, the interactions between diperoxovanadate complex [OV(O2)2(D2O)]-/[OV(O2)2(HOD)](-) and a series of 4-substituted pyridines in solution were explored using multinuclear (1H, 13C, and 51V) magnetic resonance, DOSY, and variable temperature NMR in 0.15 mol/L NaCl ionic medium for mimicking the physiological condition. Some direct NMR data are given for the first time. The reactivity among the 4-substituted pyridines is pyridine > isonicotinate > N-methyl isonicotinamide > methyl isonicotinate. The competitive coordination results in the formation of a series of new six-coordinated peroxovanadate species [OV(O2)2L](n-) (L = 4-substituted pyridines, n = 1 or 2). The results of density functional calculations provide a reasonable explanation on the relative reactivity of the 4-substituted pyridines. Solvation effects play an important role in these reactions.
